Few thoughts...
PS1 was not hard to program for at all. It was the easiest one hence why so many 3rd companies made games for it.
Gamecube games released on PS2 look better because gamecube is more powerful
All games are done on a PC(or mac if you are making Singstar :) ) then ported to consoles. Xbox360 is a lot like a PC so they are easier to port over.
In any case, you bring up a valid point that if companies take their time with games like Sony is taking with theirs, they can look amazing. I'm getting a little tired of Sony PR bullshit how Uncharted uses 30% and so on...give me a break.
There should be a device that measures systems horsepower...like for cars.
