Microsoft Tells Us What They Mean By Xbox Live on Windows Phone

"Guess we don't have to wait until MIX to have all our Windows Phone 7 Series questions answered! Microsoft's Eric Rudder, speaking at TechEd Middle East, showed off a game developed in Visual Studio as a singular project (with 90% shared code) that plays on Windows with a keyboard, a Windows Phone 7 Series prototype device with accelerometer and touch controls, and the Xbox 360 with the Xbox gamepad. Interestingly, not only is the development cross-platform friendly, but the game itself (a simple Indiana Jones platformer was demoed) saves its place and lets you resume from that spot on whichever platform you happen to pick up."

So if you're wondering what is meant by the Xbox live tile on a Windows Phone 7, this video should help explain what will soon be possible. Hit up this video, and find out! Warning: It's pretty cool!
