theres always key devs that outshine others on any format, its just that nintendo are a software house aswell as designing the hardware. Its only logical that the designers of the hardware can produce the most impressive results.
Not many devs can produce a racer in the same calibre as gran turismo, not many devs can produce an FPS as good as halo (although that is arguable)
If you look at squaresoft and their input into the formats they publish for, they almost always blow the standard through the roof, the level of graphics in FFX was absolutely head and shoulders above anything we had seen on the PS2 at that time but devs cought up eventually, They did the same again with FFXII. It make syou wonder why SE dont make their own console really, but thats another story.
I think somthing like metroid may not be matched, but it sets the bar higher for respectable developers, if nobody ever pushes a concept further then development comes to a standstill, anyone making a space FPS knows that its going to be compared to MP3 so they better not be lazy or their game wont get a look in, just as anyone making a racer for the PS3 knows it will be compared to GT5 and so on.
