As far as I am aware, FFG has proclaimed that they are not going to follow suit with TOY and reprint the map from the base game on the opposing side. I had this thought, though. Why not do as TOY did, & when they release Tannhauser 2.0, they have a completely new board in that. They then offer an upgrade pack (ALA their Talisman reprint) with the new board they released with the base game, the new rules in print form, and any new components they introduce (if there are any).
They could even offer a discount if someone were to trade in the board they had from 1.0 (You print a coupon off the website, and you can bring the board into a local game store and get $10-$20 off). That way, you don't have a repetitious map.
Just a thought I was having.
