Xbox spokesman Aaron Greenberg talks to GamePro about 3D gaming, Game Room details, and the status of CES!

* GP: It seems like one of the biggest trends at CES is 3D-there were 3D televisions and one of PlayStation’s biggest parts of Sony’s press conference was 3D PS3 games. Where does Xbox stand on 3D gaming?
* AG: We support 3D today-we’re a fully compatible 3D console, and I think it’s just a matter of developers wanting to make 3D games and consumers wanting to bring 3D into their homes. I think it’s unclear how much demand there is for that. I think it’s clear that the technology is here, and I think we’re seeing a lot of that, but it’s a pretty big investment to buy a 3D TV. I mean, it’s exciting technology, but when it will ever reach mainstream adoption is unclear to us.
One of the things we love about project Natal is that it works with every Xbox 360-we’re able to add that experience to this generation without requiring you to have to buy a new console or new TV. The simplicity of that makes it so that we know millions of consumers will be able to experience that this holiday. We do 3D-the Scrap Metal game we have for Xbox Live Arcade is on the floor, and it’s a fantastic title, I suggest you check it out-it’s made by the same guys who made N+-it has a 3D mode that you can use with any TV. If 3D becomes more popular with consumers, we’ll adopt accordingly.
