My apologies for not keeping the schedule page up to date. Part of the problem is that it's very fluid, we're state-driven, not date-driven.
As Talli said I'm hoping to roll out a second alpha tarball this week (I'd hoped for Monday but became ill on Thursday and am just now back to being more-or-less normal). Note that the schedule didn't have a slot for an alpha2. I made that (somewhat unilateral) decision based on the fact that I and others fixed a lot of bugs and added a couple of previously unported packages. We should get some more testing in by beta.
I'm hoping for a alpha2+2 weeks schedule for a beta and an alpha2+4 weeks schedule for a final release.
