Nobody here knows, or if they do, they are not allowed to release any details due to Avid's non-disclosure agreement that any beta tester would have to sign before they would be part of testing. I'm as curious as you, but that's just how this stuff works. The new MBOX Studio and Carbon are 2 examples as I'm sure both products were in some studios before we all found out. Personally, I'm still hopeful for a 004rack that can do 24 IO and sound as good as Matrix Studio and connect via some form of USB(AVB is useless for those of us on Windows machines). Keep your eyes on protoolsexpert.com as they seem to be ahead of most
