In an interview with Crytek's Avni Yerli, in regards to their future support for the Wii U hardware, the co-founder of Crytek had this to say:
The specs are very good. It's a challenge for designers, but once thought through it can add value, and that's what [is] ultimately important. Our guys in Nottingham, they are very happy with their tests on the dev kits and they're excited about it.I don't know about you guys but this sounds very good to me. Let's hope they can support a game at launch to really show what the system can do.
