I remember the last one I read from Steam.
1024x768 was the resolution to use. Now it's 1920x1080 (desktop) + 1366x768 (laptop resolution)
I'm not surprised that dual cores are still going high. I'm guessing the next one will have quad cores with a higher percentage when the dual corese become too slow to match up the needs of an average gamer.
People are also finally moving to Win7 - some prefer XP still, but the 3.6G limit to memory will start dragging at some point, and they will upgrade (which is already clearly visible).
Otherwise it looks nothing surprising. I hope not to see any 4:3 screens in 5 years though...
