Hmm, how odd! I'm a 1.0 player but I preordered ARR (don't laugh, I reeeallly wanted the goodies! xD ) and have already received my hat and minion. I also got the goggles from my original 1.0 preorder. Did you try relogging? I've heard you may have to do that if they haven't popped up in your mailbox yet.

But note that you only get preorder items for the version(s) of the game that you preordered, and I never saw anything stating otherwise. Legacy status has no bearing on what preorder items you get.

Sorry I couldn't help more, good luck!
