So people are saying Yoshi said his shirt (Scarlet Witch) was a hint about one of the new classes for 4.0. (He wore a batman shirt prior to the announcement of DRK.)

Scarlet=Red
Witch=Mage

This is the obvious assumption that everyone is going to make. However I'm seeing some people saying they may introduce a new class with similar abilities to Scarlet Witch. One of the ones I've heard 2-3 people throw around was a "Psychic" class (which doesn't even make sense, lore-wise) and I've been seeing Sage thrown around as well.
Personally, I'm hoping that RDM gets introduced to XIV because it's my favorite FF class of all time, but I acknowledge the fact that Sage seems like a possibility, even if it's a miniscule possibility.
So what do you guys think?

(Also, RED MAGE OR RIOT!)
