The tired out "Hollywood" zombie films, yeah, those are tired now, so in a while they'll be totally tired out and that fad will be over - but the hardcore zombie fans will continue making zombie films - they're too plugged into our subconscious' to stop being made.

Once Hollywood is done raping the zombie lore, the indie scene will come forth with a really good one I bet. Then of course, there's all the truly indie zombie films out there being made.
