So, 90% of the evidence overwhelmingly supports Isaac, everything up to this point except for one small tease has hinted at Isaac, especially the updated Smashified logo, and they tease a character with pink hair? (It is notable that Kumatora does play the role of both a silent protagonist and not being a silent protagonist as well due to how Mother 3 works.)
I think its an obvious troll move, especially since Kumatora's hair does not resemble Goku at all, and at least Isaac's hair somewhat can be argued that way (its a bit pointy and its actually blonde).
They're obviously trolling to try and get people legitimately surprised.
Notice how they didn't answer the question: "Will the hair be pink?" -> "We've worked a lot on the hair, yes" instead of just "Yes, the hair will be pink". Maybe it's just me, but since nothing makes sense, I'm still believing it's a joke.
Also, the comic comes from Brawl in the Family.

He said "the hair has been done for a while."
They specifically stated that they're try and avoid doing multiple characters from the same franchise, so I don't know why they'd suddenly do Kumatora now. Barring the fact that technically Travis isn't an official character, but he's still technically Mother related.
This is really just pissing me off more than anything.

The Smashified logo they teased looks jack S*** like the Mother 3 logo as well.
EDIT:
Well I guess pink is the final color? Based off of how this is worded.....

So uh...to lighten the mood, how about a comic my friend showed me today?
Reviewing that, I'm positive it is actually Kumatora, they didn't just give a GS character pink hair.
Damnit, I don't know why I'm bothered with this so much. They're just playing a stupidly annoying mind game and its really getting on my nerves.
EDIT 2:
Ok, this time they say "talkative protagonist". Does Isaac talk a lot in GS2? (I'm sure he does in Dark Dawn, but only during the brief time he's available since he'd be telling a lot about the story at the start.) I'm sure that does apply to Kumatora, but she doesn't wear gloves or have a sort of dynamic fabric, both of which do fit Isaac, and every other tease to date fits Isaac as well.
