Havok physics on Wii U will include extra features

"The platform has its own unique features, and has its own challenges as well. When we come across any new particular platform, we optimize specifically for some of the advantages that those platforms offer over other platforms, and Wii U has specific advantages that no other platform has, and we optimize directly for those, right down at the level of accessing the hardware. I think we'll see things done on the Wii U that we won't see on another platforms… I think people will be genuinely excited with the range of titles they're going to see come out." – Dave Gargan, Havok VP of Engineering
