Sorry gents, going to come in here and change all your hopes and ambitions by saying the next theme should be Zombie Survival. Zombie minifigs. ( Will ALWAYS be popular) Survivor minifigs with reversable heads for after they get infected. Wrecked/Dilapidated buildings (Think what they did with the HH and that fire set with the charred roof, only expanded) Pistols, axes, crowbars, chainsaws, etc. Basically everthing you see in other City sets, avoiding the military weaponry pitfall. Customizable barricades (Tvs, chairs, furniture, wrecked cars, etc) Modular-esque so you can collect them and build a sprawling, linked zombie infested city scene. Possible Zombies vs. Survivors play function or video game tie-in, where purchases can be uploaded or provide characters, etc for the game. Zombies.
