Surprising, unless they release her tomorrow, it looks like she's been delayed.  I wouldn't think they'd release her on the 31th, that's a holiday.  Very disappointing.  The newsletter from 5-4-2010 still exists.  That's the one announcing her.

I would hope beta testing would be finished by now.  I read one of the "tweets" on her twitter account that vendors already have stuff made for her.  If she's still being worked on, then the stuff made for her wold probably need to be reworked as well. 

Time will tell.
