“It is unlikely that anything will be made in higher resolution than 2 megapixel or run at faster than 60 frames per second, which is pretty realistic, but the new consoles are being built to last past the end of the 1080p display cycle. If we go to 4K display, which I believe is 8 megapixel, they may not have to run faster than 60 frames per second (and the size of game files clearly becomes an issue, regardless), but I believe that the processors can handle rendering faster than 60 frames per second
He also stuck by what he said and revealed that the new consoles will be able to render at 240 fps, but the viewing experience will not be materially improved.
“It wouldn’t make sense to build that into the game, but I was asked what the difference in processing power would be, and I replied “probably around four times as fast in terms of data as the current generation consoles.” When the follow up was “what does ‘four times as fast’ mean?’”, I replied with the faster frame rate or greater number of characters quote.”
