I'm not sure why people are spazzing out so much. Cake have ticked me off with a few things over the past year or so (and I've said so... but there's also been a lot of good stuff too).
As far as I can see these actually are some pretty "huge" announcements.
Porting to Mac? Absolutely a huge deal. Even though I have absolutely ZERO intention of buying a Mac or working on a Mac the fact Sonar was PC only was pretty ridiculous considering how Mac reliant/obsessed the Audio/Video world is. This only makes sense and has been asked/begged for ever since I've been here. I also see it being a potential direct positive to me as now if I actually DID ever acquire a Mac or was forced to use one I can use Sonar (without screwing around with Bootcamp) AND if I ever end up working with/for a Mac user at least they'd have the option to use/check out Sonar.
Lifetime updates? Yup... that's a huge deal and something that DOES interest/affect me. I already own pretty much everything I need that Cakewalk offers because I've been using their flagship since X1. I get by pretty well with all those tools and a few calculated third party purchases. Dropping $150-200 a year (when I'm a broke arse upstart who needs other things to round out my "studio") doesn't make sense when most of the value from a Sonar purchase actually comes from a lot of the extra doodads. I'm at the point where I mostly just want to have internal features improved (*cough* automation *cough* time stretching *ahem*) and would definitely like to see more stability/reliabilty... particularly when attempting more advanced tasks (things always seem to break when I start getting too fancy).
To be perfectly honest I was about to stop even thinking about keeping up my yearly upgrade and if that money came around I'd dump it into the base version of another DAW that handles some of the tasks I need to perform better than Sonar currently does.
However... a ONE TIME upgrade to get core improvements in (supposed) perpetuity? Yeah, that's a decent proposition. Keeps me in the loop, using what I like/am comfortable with (for tracking/writing/comping/mixing) and hopefully some of the improvements I need will come down the pipe. I've seen quite a few core improvements since the Gibson takeover that have helped me significantly. Bit of a snails pace and some things are a little too bubblegum/frivolous for me but I see things I've wanted for a while happen and continue to happen...
Which brings me to the 3rd "huge" announcement... which seems more like a bunch of smaller announcements about upcoming features (but good ones, to me anyway). This actually kind of feels more like how the old version system announcements worked (X1/X2/X3/SPlat). Like how every year or so we'd get a new release with a bunch of new high ticket improvements. We've gotten add ons and little tweaks and whatnot this past year but to me SPlat has more or less stayed what it was (except for Aux Tracks but that feels like it was part of the 2015 bundle, just released mid year).
Overhauling Take Lanes and the Browser are both worthy core improvement ventures to me. If they go well both will help me quite a bit and I KNOW people have been itching for Take Lane/Comping improvements. Lanes were half baked before but improving steadily. I'm betting the Baker's have been watching a lot of the Lanes threads and gathering intel on what's working and what isn't. I get by fine with Lanes/Comping but have most definitely discovered a lot of quirks and whatnot. The Browser though (which I've started using with much more gusto over the past year) is something I'd love to see get made more logical. Based on the prerelease info it looks like they are now actually allowing folder architecture reside right inside the main browser (instead of the weird arse method of having to "Show" the file trees in a separate browser or having to navigate in a totally illogical manner unless you custom build your own heiarchy in Sonar... WTF is that all about? lol). It looks like they are focusing on the plugin tabs first instead of the media tab (which doesn't help me much because I have so few plugins but it's likely very useful for people like Bapsi with a millionety doodads) but if they apply it to the file system of the computer so I can bounce around, rename, move, copy, etc right inside one Browser window... well that would be great (and is how things SHOULD have been done in the first place).
So yeah... if I'm your typical Sonar "recurring customer" demographic (middle aged, white guy, semi pro, songwriter/guitar player who has all the doodads he "needs" and kind of knows how to use them so doesn't want to drop MORE money on things that might be "slightly" better) then a lifetime upgrade is brilliant on my end and for Cakewalk it'll keep me around so my eyeballs are still focused on whatever new goodies they conjure up which may entice me to buy them.
I also think that Gibson has actually been using Cakewalk/Sonar as a vehicle for promoting their other products. Gibson over the past decade or so have been a MASSIVE marketing force. You see the name all over the place and obviously they are expanding their product line. Since Sonar is of course used by musician's what better target audience for your marketing than Sonar users? They have instruments, cabling, interfaces and gobs of other music stuff all under their umbrella now and seem to be acquiring/inventing more so being tapped directly into a whole subsect of DAW users turns into a self perpetuating sales machine (and vice versa... like Gibson guitar users might look at Sonar now... and so on).
So even if some departments/acquisitions lose money for a while it might drive sales to another area and is likely less expensive than advertisement (and the individual companies act as leverage for other things or can be sold as opposed to direct advertising which is like throwing money into a wood chipper for such a small market). Even just having the Gibson logo somewhere on a wide range of products in the music store or online music shops is great advertising. You gotta figure they got Cake for a good price from Roland too considering Roland was having some hardships and were kind of driving the product into the ground (oh X2... how I loathed you).
Anyhoo...
tl;dr
There have been some moves by Cake I have not agreed with and I was losing interest. These announcements seem pretty solid, logical and have made me want to upgrade to the lifetime thingie. I don't see a problem and doubt Cake are going to pull a fast one on the lifetime upgraders nor let the PC version languish for the Mac crowd. It actually might force them to yank a bunch of the ancient/bad code that causes so many problems.
