There have been rumors of a remake for Halo: Combat Evolved
by giving it a facelift into the current generation's graphics and putting some online co-op features. Well, Joystiq says they have a specific date
the game will come out and that will be November 15, 2011.
Halo first came out on the original Xbox on November 15, 2001 so a 10 year anniversary remake would be kind of cool to see. There's no new Halo coming from Bungie so this would be developed by the 343 Industries. I'm not a big Halo fan myself, but I did enjoy the non-repeating parts of the first game. I hope the remake isn't going to be a straight redo, but rather improve upon the weaknesses that were present in the original game.
