What they will do is unknown. I am an "old" style man, I don't like when a company spread rumor about unknown things. I remember Cakewalk was spreading rumor about "Cakewalk on Mac". That was at mentioned by you "lifetime" thing. Sonar Platinum "lifetime" is dead. Yet it still requires activation... I don't think CbB will ever stop ask for re-activation, the same for any future versions of Sonar/Next.
I still miss simple Cakewalk step sequencer and Matrix in REAPER. But for that I can use Maschine, which covers both (and some other) areas well, especially when used with own controller (plan to buy). I know NI also has online activation, but I gave up looking for free or offline license based instruments. Old Cakewalk staff and TruePiano are outdated. So I need NI staff in any case.
