this box will only handle outputting the TV image (split up and de-warp it for 2D plane) aswell as processing the 3D binaural audio

it won't provide any additional gpu power and it's only connected via HDMI and USB(power), so the data transfer would be waaay to slow to add to graphics processing anyway

Isn't it used to double the frame rate? I thought it was supposed to up the fps to 120, probably by techniques used in tv's nowadays.
Hopefully the specialized box will keep the display lag as low as possible and add final headtracking corrections to the image, so turning your head will have the lowest lag possibe.

no, the PS4 handles the reprojection, from what I read it's a very fast GPGPU task that uses minimal processing time right before the frame is output

and it's very different to how a TV adds in-between frames - a TV takes 2 frames and generates an image based on the differences (it's output before the 2nd of the 2 frames, but obviously has to wait for that 2nd frame to be received and for processing for the generated one to be done -> added lag), reprojection uses the last complete frame and adjusts it based on the latest tracking sensor data

Ah that was old news. (The FRC unit effectively doubles the frame rate).
From the slides in this Neogaf thread it looks like it's indeed moved to the gpu.

He only briefly mentions the psvr unit at 14:30. It's powerful, does a lot of heavy lifting, improving as we go. No info what it actually does. A true black box so far. But yeah 3D audio and extracting a tv screen image makes sense.

It sounds like reprojection is only moving the frame based on the latest head movement data after the frame is rendered. So the unit can still handle that and the optics distortion. Anyway it seems like they don't exactly know yet what it will do.
