First of all, the players on the forums have little idea what will return and what will not. Employees of Three Rings rarely chime in, and they may not even know, because plans change.

Second, don't count on special promotional items not to return. Three Rings can make them return or not as they like. I mean, if you're spending huge resources on fancy items because they'll never be available again through promotion, then be careful. Because maybe they will be available again. The fancy costumes that came out with the piercing swords were like this. People were mad when they were made available again.
