I'm so glad I bought one before they took out the backwards compatibility. As I was saying on another thread, pokemon does the same thing as WoW, and vice versa. Pokemon releases new worlds, gym leaders etc. WoW releases a new expansion featuring new worlds, new bosses, new gear etc. I'm sure some people will get pig-sick of WoW when they're on their 4th or 5th expansion and the data size gets to be out of hand. (As if 13+GB wasn't out of hand right now)
