It's probably going to be released today, but it'll probably be the same thing as with the DX11 stuff.
That is, it's released on a specific day, but instead of it being released around 12 PM GMT, it's around 6 PM.
Which means that the day is almost over before we get it, and that's not good news for me.
(And in case you guys don't know the AM/PM system, then 12 AM is 00:00, and 12 PM is 12:00)
