The potential is gigantic:
HDR, HFR, first game with 2D raytracing, TAA...
...and most of all: Base version running on every rig. ;)

What, praytell would be added by HDR, HFR or 2D Raytracing? Or TAA?

There's only so much the art could be upscaled while still keeping the laserdisk style gameplay which I honestly think is the bigger problem.
