I agree with a lot of the FIRST few posts in this thread. For this past year I also am very happy with the "model."
This PAST year was a bargain, for me at least, BUT to fully answer the question asked in the threads' title the upcoming year will tell the full story, not the past year, because; the new Cakewalk business model hasn't really been in full play yet.
In January (2015), it cost $149 to go from Sonar X3 Producer to Sonar Platinum (please no semantic gymnastics over words like rental, or subscription, or whatever). With that upgrade we ALSO obtained AD 2 with XLN Producer pak (XLN's 3-pak add in), Melodyne Essential, as well as the usual suspects like the full versions of Dimension Pro and Rapture.
We got all the above and, over this past year, we also obtained a lot of improvements, enhancements, and fixes (not everything that all folks wanted - but more than a few) and add-ons like Drum Replacer (not important to me but apparently to a lot of users it is great). So again for $149, this past year was a very good year.
As I alluded, most of us already had full Dim Pro and Rapture. I have no less than four Dim. Pro and Rapture serial numbers accumulated with various upgrades over the years, so that was no selling point, for me to "jump in" last January. Also, the $79 Melodyne Essential was not a selling point (again, to me) since, I had it from the previous upgrade from Sonar X2 Pro to X3 Pro (and actually had already upgraded to the Melodyne Editor).
However, the XLN AD 2 with Producer pak was the tipping point (for me) to jump in since I was going to upgrade from AD 1 to AD 2 anyway. That alone would have been $79 without even considering how much the XLN Producer 3-pak would have been ( I think that was another ~$80 or more).
So as I see it, I got AD 2 upgrade for than $79 (with free 3 pak add-on) AND Sonar Platinum with a year of "monthly" updates, enhancements, and fixes at a huge discount of around ~$70, again a GREAT DEAL for CY 2015!
But looking AHEAD to CY 2016:
This UPCOMING year is going to cost me (most of us) $199 simply for the PROMISE of a year of updates (aka bug fixes). The rest are ALL "maybes." Maybe new feature add-ons (like Drum Replacer), maybe enhancements/improvements, maybe TBD add-on/add-in "bonuses." Bottom-line: there is no legal requirement for Cakewalk to do much, if ANYTHING for that $199 in CY 2016.
Although there is a very real and pragmatic business reason for Cakewalk to deliver what most users would agree is worth AT LEAST $200 in support, enhancements, fixes, etc.
Cakewalk, like all companies, wants to maintain and, more importantly, GROW their customer base. They can only do that if most users think they get their money's worth and "spread the (good) word." Additionally Cakewalk wants to minimize (zero being the ideal) negative or unrecoverable "press." So Cakewalk, like most companies, is motivated to deliver for that $199.
So at this time next year you or I may end up thinking we've gotten way more than $200 worth of "stuff," and support, enhancements, improvements, and fixes for our $199. Or we may think we got very little more than a few expensive bug fixes. So the real story for CY 2016 is TBD . This will be the first time I have to lay out $200 for a year's worth of Cakewalk "maybes." so next year I will re-evaluate whether I will continue down this path with Cakewalk.
I'm not complaining at all for this past year, again it was a great deal (to me) for $149, but the UPCOMING year will tell the actual story, good or bad, of Cakewalk's "new and improved" business model.
For the record I've been with Cakewalk, and loyal to this sequencer, now DAW, software, since Mar 1989 when I bought CW V2 for DOS - I just don't show up here very often to post.
