Bump. Futuremark just sent out a press email. It seems they have run into some difficult bugs and are working them out prior to launch. As such, they "made the difficult decision to postpone the launch of 3DMark 11 by a few days."
They're doing this to avoid having to update almost immediately after release, which is preferable for us of course. No word on the new date, but they will update when they know more. We will do the same!
