Yeah pretty sure Layman said he'd finish at issue 60, and we're on issue 49 at the mo, so would have thought next year would be the ending point.
I was also wondering about the Revival/Chew crossover, purely because Chew is such a world unto itself that I don't know how putting it in the context of what I imagine is a slightly more grounded (as grounded as an undead story can be) scenario would work.
