There's a potentially decent looking Zombie board game on Kickstarter right now. It looks a little like Last Night On Earth but a lot deeper. Hopefully it's easier to play than All Things Zombies.

Actually a number of them coming that look good.
Zombicide is another with a lot of figures and such that sounds promising : http://boardgamegeek.com/boardgame/113924/zombicide
And LNoE has a new expansion coming called Timber Peak that can also be a stand alone game : http://boardgamegeek.com/boardgame/122240/last-night-on-earth-timber-peak
A new experience system and a full fire system like Invasion of Planet Earth had. I own most of the big retail stuff for LNoE, and I'm frankly looking forward to more of a fresh step forward for it (hopefully with fewer deck searching scenarios)...although Timber Peak already has an expansion in the works for next year : http://boardgamegeek.com/boardgameexpansion/122878/last-night-on-earth-blood-in-the-forest
