I'm will almost willing to bet money that they will show the release date next month along with the box art.

Not sure, but given the fact that release dates for games usually get announced a few months before the game actually releases, it's plausible. 

well, if they don't do it then they've really blown their chance

Oh yeah. I think this time we see it. It's a big event and why not announce it there?

Plausible. I'm quite convinced it will be out on the 6th.
