Why I believe Maple Story 2 will be a prequel

I would love a prequel instead of a sequel.
But, I doubt nexon would come up with a name that can define that it's a prequel. Maplestory 2 sucks pomegranate, and it would mean a sequel.

Legends of Maple Story.
Maple Story: Rise of the Black Magician
Maple PrehiStory.
