the cost of GPU power. "From what I hear ( and I trust my source on this as reliable ), the CPU chip in WiiU is almost certainly weaker than Xenon & Cell. Which is why some devs have outright refused to port their existing (in-development) PS360 games to it. I believe Nintendo indended the GPU compute support to make up the difference for their weak CPU choice, however the CPU performance is so bad that devs would be required to refactor their entire engines to get stuff working on the GPU instead, and for many dev that would be impossible on their current project schedules. " If the Wii U CPU is out of order, then yeah, the CPU will be running at a much lower clock (think about it, G4 PowerBooks back then were running up to 1.6 ghz single core, nothing close to the tri core 3.2 ghz PowerPC in the 360). I remember how disappointed devs were in the 360 and ps3 CPUs when they first launched. Without the proper optimization, they ran terribly (and how many games can you think of that actually push a console's CPU?). Regardless, the Wii was the only console to have a game that actually used physics as part of gameplay (Boom Bloxx). So yeah, can't say that I'm too worried. Actually, Havok would be fine. It uses GPGPU, which is likely why Nintendo is supporting it. well like most modern middleware it's scalable so yeah I'm sure the Wii
