I'm sure we'll see a LOT of the classic cheats along with some cool new ones. I remember long ago I posted in the wish list thread or somewhere else about an idea for cheats. It was something along the lines of entering a master cheat, which then you can access a cheat list on the pause menu. From here you can simply turn on/off certain cheats in a very easy way. Included in this list would also be a vehicle spawner cheat where you can select any vehicle in the game and spawn it as you like. You could also create your own weapon tiers, so you can mix all sorts of weapons into one.
