Which Publisher Did The Best/Worst This Generation

[JEMC]

Best.
+Nintendo (as a hole company) has done it very well this generation, both with their own games (new and old IPs) and publishing others (like Level-5's Layton series).
+Sony has also done quite well, launching new games such as Uncharted or Little Big Planet.
+Take Two, which thanks to new IPs like Borderlands, Red Dead Redemption or LA Noire, has been grown as a Co. and has been able to make profit even without a GTA game (something they couldn't do before)

Worst
+Namco-Bandai have done good games but the decision to not publish them outside of Japan has been a major mistake.
+Square-Enix. Yes, they may have done a good profit, but none of their new games (not counting what Eidos has done) has done well.
