Hmmm well
PS3 - From $600 to $300, massive improvements to PSN, Slimmer model, finally got some good games.
360 - Got rid of RRoD, several improvements to XBL, $199 entry price, also finally got some good games (it wasn't as bad as PS3, but games were lacking to start with)
Wii - Hasn't really changed much except drop to $199, most of the good games were out by 2008 so lack of games was never a problem.
I'd say PS3 improved the most but you could make a case for 360 because of the RRoD problem that they've fixed with the new 360's.
