Microsoft has been at a severe disadvantage with backwards compatibility between Xbox 360 and Xbox because of the vast differences in terms of hardware creation, but no one's really considered the possible advantages of that situation. Bungie Studios, however, seems to be the first breaking word on this.

"We're going to have more to tell you about how Halo one and two look on 360, and it's all good news," says the company.
There shouldn't be any reason to call special attention to the game's looks on Xbox 360 unless there would be a noticeable difference. Rumors have been flying backwards compatibility would add 720P support for HDTVs, in addition to cleaning up frame rates and texture issues, but no one at Microsoft or Bungie's made anything official.

A full list of backwards compatible games should be made available on Xbox.com any day now, and hopefully we'll learn more about the enhancements the Halo series (and potentially many more original Xbox games) will receive next-generation.
