Metro is a design philosophy, not anything that can be infringed. Microsoft is actually heavily evangelizing Metro, and would probably be pleased to see the competition playing catch-up for once. That said, individual interactions can be patented, and OUYA would definitely have to steer clear of this. I would say the biggest issue might be the colored button graphics representing the actions to perform; this looks and feels like Xbox, and would probably be a grey area for sure.
