It's becoming increasingly difficult for us to shamble out of bed and avoid stubbing our toe on some unconfirmed list of Xbox 360 features, fixes, enhancements and/or tweaks meant for the system's Spring dashboard update. Though we usually avoid the ones promising "full compatibility with Metal Gear Solid 4" or "online racial slur filters," this latest one proved unavoidable. Thank you, dear tipster, for leaving a concrete block at the base of our bed.
You'll find the "incomplete" list of unconfirmed features after the break, though we'll draw your attention to two in particular. "Calibration options for motion sensor devices." That certainly brings to mind the numerous Newtonian rumors of a Microsoft waggle wand we've encountered over the last few weeks. As for allowing games to "store installation data on Storage Device for faster loading?" We'll go make a sandwich while you guys discuss.
Update: Microsoft says: "We don't comment on rumors or speculation, but what we can tell you is we've never seen this list before."
