I've not purchased it yet but SFLogicNinja did a really nice overview. I've got to tell you - it's looking pretty good to me. Especially if they've fixed some of the long standing bugs, but to be honest I never had as much crashing issues as some other users. Some folks will say "oh DAW X has had that feature for 2 years" and that might be true - but I already know so much of the ins and outs of Logic that I'm excited. I'm especially pumped about it only being 64-bit. The old Logic drove me crazy with having certain features (like export audio to movie) under 32-bit but not 64-bit. Really created some headaches if I was scoring a large session and wanted to show the client my work embedded in the movie.
I'll probably be buying it within a few weeks myself. I always like to let the dust settle just a bit to avoid any major bumps.
Hope that helps,
