First xbox brought online gaming so that's not really something 360 really shape online gaming.
What it did bring to the table was unified achievements/trophies. Something that will be in all consoles from here. Correct me if I'm wrong.
PS3 brought bluray discs which will carry on to the next gen. This also affected the HD war between HD-DVD and Bluray so I would put the HD twins even.
The Wii. Hate motion control and it seems pretty much dead to me. I hope. So I'll just put it in last place. Same with a bloody tablet controller. Games using the classic controller were still be good on Wii so this isn't a broad attack on the Wii. Just motion controls.
