Microsoft: WP7 is handheld Xbox

3DS is on the way and Sony’s handheld masterminds are working on multiple devices, but don’t expect Microsoft to announce a portable Xbox any time soon.

Speaking to Kotaku at CES, the company insisted it has already launched a handheld games platform in Windows Phone 7.

This is our mobile platform for games,” said Kevin Unangst, senior global director of PC and mobile gaming at Microsoft. The same people who make the Halo game, the same development folks, work on this. This is our mobile console.”

Key mobile players such as Electronic Arts and PopCap have already pledged their support to Windows Phone 7, and Microsoft is trying to muster support from Epic Games. More than 60 Xbox Live-enabled games have been released for the service since it launched in November, with phone sales to the tune of 1.5 million.

Microsoft also announced a number of WP7 games – including Fable Coin Golf and Pro Evolution Soccer – at CES.
