'Big E3 2009 announcement' on X-Play tonight

The guys at G4 just dropped this into my inbox…

Do not miss X-Play tonight at 8 PM ET. Along with reviews of three huge games (Fable II, LittleBigPlanet and Dead Space) and an All-Access look at Mirror’s Edge, X-Play is making a truly huge announcement concerning the next Electronic Entertainment Expo. We’d love to tell you what’s up with E3, but we are honor-bound to keep it to ourselves until tonight, when all will become clear and lives will be forever changed–okay, maybe not forever, but it’s a pretty big deal, and you can be first to know the scoop. So don’t miss the show, tonight at 8PM ET on G4!

I can’t remember the last time I sat down to watch X-Play, but I’ll be doing so tonight. Anyone care to take a guess as to what the announcement is? I’m voting for an ‘open to the public’ show!
