With Canon showcasing the 120MP sensor the current lens would show its weaknesses so I'm not surprised they are upgrading it lets hope it usurps the Sony lens.
I doubt we'll see a 120MP APS-H camera, though we might see an equivalent 200MP FF and/or 80MP APS-C. IMHO, we'll see neither, for several reasons.
First is optics price/performance ratio doesn't get better the way electronic's does, and the market wouldn't bear the prices.
Second is the question of how useful it would actually be. To get that much detail, photographers would need to shoot with wider apertures to avoid diffraction, better stabilization / shorter exposure to prevent camera motion blur, etc.
[Yes, it would still, as surely as CN-E lenses with a 5 digits price tags do.]
Third is the market already wakes up to the fact the need for such a high resolution is niche with extra costs.
