I agree.

I'm not completely sure, but didn't Mashima even call it a "sequel" at some point?

That might be a sign for it getting an additional title, like how Naruto is split into just "Naruto" and "Naruto Shippuuden" or how Magi's 1st season is called "Magi: Labyrinth of Magic" and the 2nd "Magi: Kingdom of Magic"
