This is the set up. 10k video per eye. Obviously overkill considering current VR headsets. But we can always downscale until the tech catches up.

I was lucky enough to have worked on this project at least on the capture end of it. those figures sound about right. likely those figures are the lump sum of all of the assets it took to create the piece.

No, it is. The 475 camera rig takes video and images at a VERY high resolution and piecing all that together in VR equates to a massive file size. And keep in mind this is for a 5 minute project.
