The developers of the 360 version of Quake 4 have done an admirable job of bringing the original game's assets over nearly unchanged--we couldn't tell much difference between one game or the other, from a visual quality standpoint. But the console version's frame rate has suffered in the transition somewhat, so we hope the team will continue to optimize it, now that the final Xbox hardware is freely available.

However, Activision was kind enough to confirm that the game will support eight players on Xbox Live.

We also got a juicy tidbit about the special editions of both the PC and Xbox games, each of which will retail for roughly 10 bones more. The 360 special edition will contain the full game of Quake II, so you can go back and see how the story began, and this version of the game is said to be graphically enhanced to some degree (though specifics weren't available). The PC special edition won't dress up any old classics, but it will have something potentially much nicer: every Quake game and expansion pack ever released, along with the new game, all on one DVD.

So I guess there will be Special Editions for both the PC and Xbox 360 versions. Gee, isn't $60 enough for some extras?
Also, WTF WTF WTF @ only 8 players on Xbox Live. This alone is making me consider getting a new PC card to get the PC version of it. ATI, release the damn cheap new cards soon!
