Today is the start of Microsoft's X06 event, and we already have a hefty chunk of new information coming out of it. I'm actually watching Microsoft's press conference as I type this, and by the way, they're demoing Assassin's Creed right now and it's beautiful. As I understand it, the whole conference will be up on Live later today.

• Bioshock will be a PC and 360 exclusive.
• Marvel City of Heroes developer Cryptic will be bringing a Marvel-comics themed MMO to the 360 and PC.
• Rare is developing a new Banjo Kazooie. I guess the Killer Instinct rumor proved false, but thank God we've got a new Banjo.
• Rockstar will be offering two 360-exclusive downloadable episodes for GTA4 in a few months after the game's initial release.
• The HD-DVD player will retail for $199 and ship in November in America. For a limited time, it will be bundled with the HD-DVD of King Kong.
• PGR4 is in the works. Duh.
• Splinter Cell 5 will be an exclusive to the 360.
• Half Life 2 will be making an appearance at X06 on the 360.
• The original Doom is up on Xbox Live Arcade today, for 800 points. All four episodes included, along with onlinedeath match and co-op.
• It turns out Microsoft shut down that fanmade Halo RTS because Bungie is making their own, called Halo Wars. There was a trailer during the conference that will undoubtedly hit Live soon. (or you can watch it online right now)
• Peter Jackson has established a new studio called Wingnut Interactive that will be working on a new Halo game.
