Have they changed their minds on the whole "No offline mode" ? Kind of a deal breaker for me
We probably won't end beta until shortly before release, and traditionally we've tried to announce release dates about two months before release. I couldn't speculate how invites might ramp up or down when the beta finally comes to a close, it definitely is not coming to a close yet though.
I posted a link in the Diablo 3 thread with Bashiok @Blizzard saying that they normally announce release of there games 2 months in advance.
