Yes dude melee must make a miraculous return, but more like Vice City with the hardware stores and all the tools. I think the best melee for the next GTA would be an extension of how you can pick up trash stuff in the game and throw it at people, except this time would be maybe broken pieces of wood, etc. Anything laying around that could be used as a weapon. PLUS hardware stuffs, especially chainsaws. Chainsaw made GTA seem more "mature" in that, it was like SCARY.
Of course there needs to be also be some incredibly intensely detailed awesome gore if there's going to be chainsaws.
