there's one more beta which is beta 2 after that its the
final version.
beta 2 might be release i think maybe this month and if
they don't release this month or after that we might
expect either beta 2 or final version on after the
expiration date. (Simply a guess) but it would be nice if
they release it this month.
Seriously, the options right now are either another build of Release
candidate, or the final release willhappen. I'm not thinking that MSFT will
leave you hanging.
