I guess it will be ready when it's ready 
That's actually the official release date
First it has to go to alpha. Then the question is how much will surface that's problematic, which will determine how fast it moves into beta. Then the question is how much will surface in the beta that's problematic, and what's needed to do a full port. And you never know whether Apple will move the goal posts; that's happened before with the AU plug-in and other specs.
I can't imagine any way Cakewalk could make a definitive statement on when it will be available given that it's this early in the process, but then again, I thought they'd never come out with a Mac version...you never know what new technology will come around to change everything
