At a CES keynote, Xbox boss Robbie Bach said Natal will be released for the 2010 holiday season, ie in the run-up to Christmas. Hufford said the team had demonstrated at E3 that the technology worked, and now "we've asked the development teams to concentrate on making the games." Hufford said that the Xbox 360 did not need an upgrade to support 3D games -- "Avatar is on Xbox and we have a 3D game, Scrap Metal, in our booth right now" -- and nor would he commit to offering a Blu-ray drive. Indeed, I couldn't even get him to speculate about moving the 360 forward to a more modern chip technology. This would reduce the Xbox's manufacturing cost and also produce a console that generated less heat and cost less to run -- benefits that have already accrued to Sony with the launch of the PS3 Slim. It should also be more reliable.
