"In the case of the Luminous Studio, we're probably not going to be bound to any particular platform. PC already, probably PlayStation 3, Mobile, iPad tablets also browser and cloud as well. Not just next-gen - we can scale." - Square-Enix chief technical officer and Luminous demo producer Yoshihisa Hashimoto

Comments like this seem to indicate that Wii U should be in the running for Luminous Engine support. If PS3 can handle it, Wii U should be able to as well.
