I like consoles, I don't need to upgrade my PC for every new game that comes out. Yeh for consoles the up-front costs are high but for those who have managed to stick it out for two years on their PS2s the rewards are plenty if they get a PS3 now. Besides, I like having a console that won't be replaced by a newer model every 2-4 years.
On topic, I'm never sharing my class selections with anyone but haas knows it has something to do with a shotgun.
EDIT- Here's an awesome video I found on Joystiq.com the other day, answers some questions about the not-so-well advertised features in COD6.
