I also wonder how DF staff are going to find out the resolution of any given game when they are over 1080p. I don't think there is going to be steps to count..Yep. I honestly have no idea why anyone thinks 8k will ever be necessary for the home.
Additionally, Digital Foundry retro looks VERY promising. Hopefully they won't only focus on retro consoles, but also arcade motherboards and machines from the past, like the Model 1 and Model 2, ZN-1, Naomi, etc etc etc.

Plus, I wonder if games like Gran Turismo 4 and other legendary games at the time quite delivered in the framerate department. People used to say how incredible Gran Turismo 4 was running at a flawless 60 fps, but I certainly doubt it was flawless.
