This simply made the most sense to me as I love Bethesda games, but didnt own a platform that would they favor. And since I didnt have the cash to build a rig that would handle skyrim I opted for the 360 (the dawnguard DLC helped this decision as well). I hope that one day Bethesda will get better people to code for the PS3, but I highly doubt it.
p.s. I am no console fan boy, and no comments above should be taken as such. I am simply saying that if you love a game that you know the developers are especially "talented" at coding for, you should probably move to that platform. I am keeping my PS3's and god speed to all who continue the fight!!
