I'm not going to jump on that as I'm not quite that trigger-happy but I do have an old version of Artist which I can update to Artist 3 for a whisker over 20 beans in the same sale, that seems like a reasonable move just for insurance purposes. I never spent much time with it but I gather some people like it a lot so good to keep a foot in the door, I can play around with it and see if we get along. They have fairly regular sales so moving up to the flagship is always an option.
Ableton looks to be on solid ground for the moment, as mentioned elsewhere I was at their Loop conference last weekend here in Berlin (I have some friends in the company) and it was great, I saw and heard some very cool things, there are a lot of creative people in the world and that community is a pretty good example. I'm keeping a foot in the door there as well. The upcoming version (Live 10) looks pretty spiffy.
I have also always had a soft spot for Reason and was already toying with upgrading from my old license (7) as there's a lot of new stuff there at this point. It's a fun, creative environment, some great new instruments, Blocks are cool, the built-in time-stretching thing is kind of wild. Would miss many things about Sonar but there are many other toys there to distract me from that, and with VST on board now...
Reaper would be the only other one that would tempt me, again I've installed it and looked it over but never done any work in it (or bought a license). I gather it's pretty full-featured at this point.
Plus, as others have said, Sonar ain't dead yet, it still works here. But for how long? For... how... long? (Sorry, just felt like channeling William Shatner was the thing to do there)
