Actually, Greg, it looks like for "Operation Annihilate!", the position of the two tables were simply switched from how they were laid out in Seasons 2 and 3.
Right--like I said.
Also, at least for "Operation: Annihilate!" it looks like the edges of the table are the ubiquitous light blue, rather than the plain "wall gray." You're probably trying to give it a Third Season look, but having these blue edges might be worth considering. I think it might make the set "pop" just a tiny bit more.
