Well, as much as this whole deal sucks, with not getting any support for a $1,000 software package, it doesn't exactly FORBID present Logic PC users to continue using their software. They will probably keep releasing PC updates until September 30th, and HOPEFULLY the final Logic PC version will be good enough to hold on to for a couple of years. If it works fine, you shouldn't have to upgrade until it's really outdated... THEN you might consider switching software packages, or if you're really stuck in the Logic swamp, spend a million dollars for a Mac.
So please folks, don't panic - it doesn't HAVE to be the latest version to work... especially if you're a HOME recorder.
I hope what they say about Samplitude living on is true. I love that soft.
