Although Microsoft's Tokyo Game Show presentation of
Space Invaders Extreme and
Beautiful Katamari running on the gesture-controlled Project Natal tech were much-buzzed in the consumer press -- as was Natal-equipped
Burnout Paradise at E3 -- they're exceptions, not the rule.
Microsoft's Kudo Tsunoda
told consumer weblog Destructoid that the company isn't readily able to "patch" existing Xbox 360 games to work with Natal, and that the event demos shown this year required significant alterations to the game's code.
So if publishers want to enable current titles to work with Natal controls, they'll most likely have to re-release updated versions of their games in their entirety.
Microsoft presented demos of third-party publishers' games running on Natal by itself making the heavy edits required to allow them to work.
