I don't know how much it would take, but I would like enough so that all of my lenses are truly glass limited at all apertures. I hate it when cheapo electronics limit my expensive glass.
When pixel densities get high enough (and I don't know how high is enough), and when data rates can keep up, the reach advantage of smaller sensors will disappear. When this happens I think there will be no reason for a less-than-full-frame pro body, and APS-H will go away (though it might do so sooner).
Higher pixel densities will also make extenders less useful (far less so, IMO). I wonder how many people would use them with a 100mp sensor?

Indeed. Just imagine a 72x48mm sensor in a body the same size as a 1D, with an all-new line of f/2.8 lenses. They would have the same DOF and amount of light as f/1.4 lenses on 35mm, but would be much sharper for the same cost. Throw in a gigapixel or two and I'd be in heaven.

I could just face the couch toward a different wall and pretend I'm on holidays constantly. []

Anyhow, I *can* imagine []

With slight modification, the EF 200mm f/2.8 would easily cover a 72x48 image circle, and quality and price are really good ($760) compared to a theoretical 100mm f/1.4 (which would probably not achieve the same quality even at twice the price, as we can see from the 85mm f/1.2, 85mm f/1.4, and similar lenses).
Look at the 50mm f/1.4 vs 100mm f/2. I would guess that the economy of scale are about the same (probably the 50mm is favored a little), but one has much higher quality for a similar price. If the 100mm only needed f/2.8, it would probably be a little cheaper still.
