What? You need a larger sensor for higher resolution? The Nokia smartphone has 40MP...come on. What needs to happen is make the denser res sensors better and less leaking from pixel to pixel. Also better technology like Foveon sensor (I think Canon was looking into that possibility).
There also becomes a point where the resolution game gets to a stasis level...don't know if that is 45MP, 55PM, 100MP...
Just getting to the Nikon 800 MP level would be a win and they'd grow their market share for sure.
not sure if Canon should buy Hassey, but perhaps they should buy a portion and allow Hassey access to their sensor and digital body technology.
If we look 5-10 years out, 35 mm format bodies will be maxed out with resolution and FPS. 25-100,000 ISO will become nearly noiseless. Where does Canon (or Nikon) go from there?
An increase in resolution will require a larger sensor. Challenge for Canon to get consumers (pros) to switch to MF is that the current lenses will not (most likely) work on MF bodies. So even if Canon came up with a $10,000 MF body, another $25,000 (or more) would be required for a new set of lenses.
