I'd love zombies but i doubt they would give us a great gameplay like that for free (look at plantsims and ghosts?) and they need to be very diferent from TS3 and more fleshed out if they want most of the community to enjoy it. They could be featured in a zombie apocalypse pack, a Haiti vacation pack featuring voodoo and zombification, elders/funeral pack with the "bring back loved ones" and family centered things, or a reimagined Strangetown pack centering in death storyline, bringing old stories from PC and PSP like Grim Reaper and Olive's relationship, Nervous' tragedy, the zombies from Paradise Place and Ophelia's meetinghouse, the ghosts from Espiritu Estate, Hazel's problem (now a curse?), and other new stories they could explore.
