A thing that came to mind regarding Sony and Nintendo jumping into the motion-control business, is that it allows them to have third-party developers who make exclusive Wii games utilizing moion control, to also develop for the PS3 and 360. However, since the basic opinion of third-party Wii software is that it isn't all that, and not worth the time of anyone.
Anyone care to comment here? Is Wii third-party software notable? And would Natal and Move be effective for getting copies of Wii third-party titles?
