We will definitely be talking about some of the graphics tech at SIGGRAPH this year, and I'm sure we'll be presenting more in the future.

I don't know what functionality the WiiU supports, but the 4.x compute shaders in D3D11 are pretty gimped. You can't write to textures, you only get one output, you're limited to what regions of...

That's actually quite the opposite for cases where you have too many triangles relative to your pixel shading resolution, since you'll end up under-sampling which results in nasty shader aliasing....
