Wow, this looks neat... apparently there's a new four part comic series coming out soon that has the Ghostbusters (including a new female member) traveling through TIME. Apparently they run afoul of some pandimensional being who banishes each of them to a different era (and, I think in at least one instance, a different reality).
Looks pretty neat, I haven't too many comics of late (with the exception of getting the Hack/Slash collections) due to lack of funding, but I may have to pick this up.
