Seems like they're preparing a new part of Time Temple.

As for the Maplestory 2 aside, I'm in the camp that believes Maplestory 2 will have little to nothing to do with the original Maplestory. To continue after any specific plot point in the original would mean that the original, obviously, could not continue past that point.
If the original couldn't continue, then, plot-wise, it dies. That's a bad situation for an MMO to be in.

I know you're right, it's just....how do I put this. I'm in this sort of place right now where I want to get this whole Black Mage thing over with, because there's just SO many ways they could keep us guessing for a very long time, and my control freak personality simply wont stand for that. While at the same time, I can't have this mentality without also coming to the realization that Maple's going to end, eventually. I guess I'm letting this confliction influence my opinions too much...
