While I loved third person with infantry combat in PS1, I do think it should go away in PS2. However, I still ground vehicles should be able to go into third person in PS2 so that they get get an idea of their surroundings an don't get stuck on shit.
Higby's argument of vehicles "camping" or whatever it was with the inclusion of third person is bogus. There was third person in PS1 and vehicles didn't hide behind buildings waiting to pop out...And even if they did, who gives a shit?
Give ground vehicles third person
