Latest Sprint teaser tweet all but confirms February 24th announcement is for Windows Phone 7

How many mobile platforms can you think of that integrate "with your home game console, like Xbox?" Unless we're completely spacing something out, the answer is one: Windows Phone 7. We'd already figured the Thursday announcement that Sprint has been teasing this week on Twitter -- and that little Arrive leak all but confirmed it anyhow -- but if you needed any more evidence that the phone formerly known as the HTC 7 Pro would be formally announced in CDMA guise this week, here you have it. We'll know more tomorrow, hopefully.
