Combine this with the Atlus co-developed Fire Emblem cross-over, and things do get more interesting. Hopefully Nintendo are planning to do this with other developers and developers outside of Japan.
EDIT: Namco-Bandai are also majorly involved with Smash Brothers, and Nintendo are obviously co-operating with Platinum to varying degrees in the shape of Wonderful 101 and Bayonetta 2.
