The inflection point for diminishing returns appears to be the PS3/360 generation

[JoeFlex]

We're at the start of the generation. What did you expect? X360 games were not very impressive, at all, until Gears. PS2 gen 1 games looked awful, and the last few games on the original Xbox and Gamecube looked marvelous (even GOW2 on PS2). Give this gen some time.
