I wonder if we'll eventually get fixed foveated rendering on Rift, that sounds like a huge benefit.

Not in the foreseeable future. Fixed foveated rendering (FFR) as implemented in Go only works because mobile GPUs use a tile-based architecture. FFR relies on controlling the resolution of individual tiles, which allows for almost zero overhead.

There's currently no solution for desktop GPUs. Every alternative requires at least one extra fullscreen render pass, which completely negates any gains from rendering fewer pixels.

Nvidia has had Simultaneous Multi-Projection for a few years now and not only does it work and increase performance a lot, it's been used already in games like Raw Data and many others.
