MapleStory 2, welcome.

Seriously? We know nothing about gameplay which is the only thing that actually differentiates the game from others. Complaining about classes that are fundamental to the MMO genre is a silly argument right now.

Because they are leaving a format where they have reigned absolute supreme for a decade. They are going up against hundreds of games that have similar art style and almost identical classes. I seriously doubt that they will surprise us and do something brand new when it comes to mechanics, so how will they make people interested?
Veterans from MS would have to be complete arse hats to throw themselves into it with nothing but the utmost sceptisism, and for people that never played the first the name itself wont do much to catch their eye. Just look at the travesty that is Ragnarok 2.

I do agree that it is too early to draw any final lines, but hell if it looks promising.
