I am for the following reasons
1. 360 is my lead system
2. I care about achievements alot more than trophies (though I admit they are pretty much the same I have a beastly gamerscore so I like boosting that)
3. I think no third party should make console exsclusives so I'm supporting them for the multi-plat
4. What can I say at the end of the day I love PS3 but the Xbox more so thats where my support is going when given the option.
5. I like the 360 controller alot more.
