All of the above. But I doubt we will ever see the Pelican, Phantom and Scarab. But I would love to see the Scorpion Tank and Hornet in the maps officially and not just on forged maps in custom games.
a giant map like sandtrap but instead of the elephant with its only good quality being the horn of doom two scarbs that would be on either side. Trying to destroy each other with little people running around underneath just sounds awesom to me. they would also make a good assualt gametype were thay act like the ones on campaign with the leg weakness but you plant a bomb in the back bit instaed of shooting it.
The only reason I didn't want the Troop Hog was that the fact only Marines can ride the three seats in the back of it. If they made it to where Spartans and Elites could, I would have wanted that.
