IIRC, there has been official word that there is no other map; they've only ever meant to refer to the Avengers map.

I received Official Word. There will be another map for week 5.

Where is this "official" ruling/statement that you must use the Avengers Map? We've been using them, but I don't recall seeing it anywhere official?

Maybe the Week 5 map is 10x10, all hindering. Take that Surfer

Our judge had at least 4-5 tank maps and he had also given out free maps to regulars the prior week. Our judge is PIMP.

I know that we had a sealed tourney at Dragon-Con back in 2002 and we were allowed to switch figures between rounds (restricted to our pulls, of course).
I do not know when it changed, but I do know that "sideboarding" was allowed then. If it was just because the tourney rules hadn't all been worked out or whatever I don't know.
Either that, or the judges all let us cheat like fiends, and said we could do so if we wanted to.

The new maps weren't sent by Wizkids - they are packaged in each, unopened case of Avengers. For every two bricks, you get one Air Base map. If your venue ordered the appropriate cases for the tournament, you should have at least five maps (being that the order was a minimum of five cases - someone correct me if I'm wrong here). I think it was a smart set-up on their part - a case is enough to supply two people with enough boosters for the series of tournaments; tossing the map in gives those two players a playing surface.

I kept enough maps for us to have several to use for playing, then gave out some extras as Fellowship prizes and to those who bought their own cases' worth of boosters.

So, if your venue has no maps for you to play on, I'd call into question what they did with the ones that came with the boosters. While I suppose it possible that Diamond/Alliance stripped all of the maps out of the boxes, I find it highly unlikely, since I've seen all of our cases come in sealed and have spoken with people at several other venues who have all found their maps in their cases, also.
