Since we're all guessing: I think Cakewalk will consolidate Sonar Artist, Pro, and Platinum into one product. This will simplify product development, documentation, testing, etc. We've already been told that the majority of the customers are Artist. To get a better revenue and up-sell stream CW will benefit by everyone having ProChannel, and seeing the benefits of the improved work flow and functionality.
SPLAT members are probably the most vocal (though a small part of the revenue stream), so we're been thrown a bone with the lifetime membership, so we don't get too irritated that the Artist members get the essence of Platinum at a "reduced" cost.
I guess we'll know in a few days ...
