According to Joystiq, the rumoured Halo: Combat Evolved remake is supposivly arriving this holiday season on the Xbox 360. And it won’t be a HD update, like some of the PS3 games. It will, apparently, be a full scaled down game, and sources have revealed that it will have new art assets (almost as if this is a brand new Halo game).
However, it was recently stated by 343 Industries (the new owners of the Halo franchise) that there would be no new Halo game in 2011. The remake, if real, is also said to support 3D (droooool) and support 1080p resolution.
The game is said to be released on November 15th, 2011, which would be 10 years exactly since the very first Halo game was released.
