Wow, I just thought of something... what if some World of Warcraft expansion allowed you to visit Pandaria? That would be awesome. So many pandas. This thought was stirred by my Pandaren wallpaper, currently on my blue/green wallpaper machine...

How are WoW expansions going to work, anyway? You have the expansion, but the other person in your party does. You get to a new area in the game, and the other person just hits some invisible forcefield that you pass right through... that would be kind of silly. There are a lot of unfinished areas on the two current continents; I wonder how many of them will become free content (like the two new Battlegrounds zones) or if some of them will become expansion-only areas.
