Sony Ericsson’s just-announced Xperia Play is set to bring an amazing gaming experience to Android fans around the world, but mobile gamers might want to think twice before signing those two-year contracts. In fact, we hope you’re sitting down, gaming fans, because Microsoft on Monday demonstrated some pretty impressive forthcoming Windows Phone 7 features at Mobile World Congress. The demo, which is just the tip of the iceberg, shows us what might happen when Windows Phone 7 meets Microsoft’s Xbox 360 and the ever popular Kinect motion-based controller. The results, though exhausting, look pretty amazing. Hit the jump for Microsoft’s demo video and while it definitely looks awesome, don’t get too excited just yet — Microsoft notes that this is just a technology demo and gives no real indication of when we might see integration of this caliber.
