There was talk on twitter, yesterday, about one being due in 1 or 2 days. This contact has been spot on thus far. My only concern is that Gabe has been very quiet on twitter. He is usually dropping hints, but he hasn't been active for a whole 24 hour period, which those who follow him know, is unusual.
The desktop Redstone was flighted early, accidentally (?), according to Gabe. So I guess web sit and wait. Stranger things have happened on a Friday though. There are also rumblings of Redstone Release coming earlier than expected.
