It may not be Halo 3 news, but it's the next best thing – Bungie has announced that not only will the first two Halos be Xbox 360 compatible, you'll also get some graphical enhancements.
To celebrate Halo 2's one year anniversary, Bungie announced that the games will be able to exploit the 360's scintillating hardware by including widescreen support, 720p (progressive scan) and anti-aliasing, which helps smooth over any pixellation.
To see the effect this has, check out the comparison shot above. The left-hand shot is in 480p, while the right is in 720p. It's by no means revolutionary, but the extra clarity could help you nail a few more head shots (particularly on split screen).
It also helps to clarify the broader question of whether the Xbox 360 will be backwards compatible with old games.
The problem is that existing software needs to be recompiled due to hardware incompatibility – the current Xbox uses an Intel processor with NVIDIA graphics, while the 360 has an IBM PowerPC affair with ATI graphics.
Halo was the obvious first choice for a re-vamp, and Microsoft has announced that it plans to make all the 'top' Xbox games compatible at launch. Ultimately, it plans to make every game compatible, with no charges for 'new' versions required.
This is good news in light of recent reports which quoted Sony spokesperson Reiko Sakamoto as saying that 'it's hard to say the Playstation 3 will be 100% backwards compatible, but we aim to make it so as much as possible'.
