There are so many vehicles, but obviously we are not going to get them all. A few things I would like that weren't in Halo 4 are the Scarab, Hornet/Falcon (any UNSC aircraft), Locust (maybe) and any older vehicle such as the Spectre from Halo 2 or the Revenant from Halo Reach. Hopefully they will bring at least one thing we like into Halo 5. I feel there are going to be quite a few new vehicles in Halo 5.
