Sorry if I missed anyone (and I'm sure I did), that's the best I could think of :p
Anyway, for me, deciding between Sony, MS, and Vivendi was insanely tough, though I'll have to go with MS (because of course, I am teh l337 s3xb0x f4nboi!11 :)). If Vivendi also owned Valve, aside from Blizzard, I would've went with them, but with just Blizzard it's a much harder choice.
