Yeah that's a good question :)

The only things I can think about is Mirror's Edge and maybe watered down RPGs like Mass Effect , Oblivion and Fallout 3 but you say those are RPG.

No fighting game section.
May I try?

Xbox 360: It certainly can handle a fighting game, but the D-Pad is too inaccurate to control a character very well. Developers need to work on making playing with the analog stick easier.
What they need to do is to get a bit out of the traditional fighter mold, make a game more combo ritch and accesible with less button mashing. using the buttons more to connect combo moves and relying less on the stick. if there's Killer Instinct 3, it should go this path.

PS3: The PS2 before it was the home of fighting games (DoA, Tekken, Soul Calibur), so it follows that the PS3 would be a well designed fighting game console. The D-pad certainly helps.

The system is home to more traditional fighter games thanks to the controller, so the safer bet in on the PS3 when developing a game of this genre. The only difficulty is that a new franchise has to be far more creative than a well known one.

Wii: Again, with the Wii, the developers need to focus on a different kind of game, not unnecessarily including waggle. Super Smash Bros. Brawl is a great example of what a Wii fighting game can be.

Wii fighter games should be more dynamic than on any other console, not in the controls but in gameplay. Doing more things in battle and many more ways to own your opponent is a lot more appealing. I will not be surprised if Power Stone Hits the Wii

You haven't played it?
