Aren't there converter plugs for using an PS2 controller on an XBOX, and vice versa? Just go get one of those for whichever one is your favorite.
The entire point of each company having their own product is to be different. Especially with the Revolution's controller, its just another way for every console to stand out, be noticed. Because of that, you couldn't convince even two of the companies, let alone all three to agree on a single controller model.
