Tough question. All depends on how you define "revolutionary".
I would have said Wii, but now that the next-gen consoles are out, it's obvious how little it has had an impact on them. I'd probably have to say PS1, for laying down the blueprint for modern consoles and causing a huge explosion in the popularity of gaming.
Edit: I guess the NES is similar to the PS1 in what it did for 2D gaming and its popularity.
