How about this scenario:
Mike said TWD was sharing a SS with an as yet unannounced original. We know 24 is the SS that two houses are going into.
But we have just assumed it's the house rumored to be Ghost Town. It may well be that house, but consider that Mike made that statement at a time when the only original mentioned was Cobweb in Tent 1. what if Chance is in 24 with TWD?
Then Krampus (if it is coming) could be in Shrek.
And Ghost Town in the new tent.
Somehow that seems to work better for me, although that doesn't mean it is what will happen.
