Currently, during the action phase when a player buys a building, the next building tile is not revealed until the next round. I believe the rules say to reveal the next building in the stack right after the purchase is made.
I know that it probably isn't a big deal, as this only affects the action phase in which not many player choices are being made, but I was recently in a game where that information would have been beneficial for me.
(It was a two player game, and I was sitting on a bunch of building bonuses. On the action phase, I was second player. First player had bought a building already, and I was about to buy one of those cards that give everyone items based on a dice roll. So I had first pick of the items, but I found myself in need of knowing what the next building tile was, so that I could make the best choice.)
