MS innovation really only applies to Kinect/body imaging and achievements.
Sony innovation really is non-existant. Controls same. Move is copy of Wiimote. Online/power is natural extension of last gen and what MS did. Bluray isn't a gaming concept or innovative as MS360 did same games on DVDs.
Nintendo had multiple innovations that have been continued and expanded by others and themselves.
1) dual and touch screen combined with buttons. (DS series and WiiU)
2) motion controls (ms innovated on top Wii by adding intelligent camera)
3) 3D glass-less gaming (3DS really did it right, its just proven to not be a big thing)
4) social connection (miiverse > than just adding in fb/tw)
