Not every LTM thing is going to be huge and splashy. Some are going to be merchandise things, like limited edition pins or ears. That may not excite you, but the people who like that kind of thing will be thrilled.
Me, personally? Not all that excited about "long lost characters". But I know other people who are ready to hop on a plane with 24 hours notice if it means they get to meet some character they don't have in their autograph book yet.
Different strokes.
