Oh god... why is Petey here?

Did anyone else read about the multi-team thing? It looks uber sweet but the best part is I won't be confined to the unholy damnation of the realms of only Red and Blue. I soooooooo hope the other colors are green and brown. Green will remind me of the outside when I get re-super-addicted to Halo and Brown will remind me of Steve Harris since his real name is Brown Bill because he is Indian and he doesn't play with us anymore.
