To bring a dead thread back, and albeit..in wondering (And to do the obligitory "Replace Shrek 4-D with anything") post, Andy..might be knowing something.
If Comcast and NBCUniversal are to per say, bring an IP back to the table, then..who's to say they may be looking at putting Off The Leash in Orlando? And in this case, in Shrek 4-D?
It would actually not take that much space, as they can fit it if they go with a Hollywood style layout of one floor being queue, and the other being the ride. And if they're looking for options already at the "basically finished" stage.
