A new trademark for Microsoft has popped up under the name Roboraid. Originally spotted by Dualshockers, the trademarked is listed under video game software but no other information was provided. It was filed just five days ago January 11th, so we'll have to wait until more to find out.
It's not quite "wait till E3" territory yet, but we should definitely hear something before then and let you know as soon as we do.
