I have NO idea if he is coming with a second head. There are a bunch of spots in the video where I just can't hear what's being said (people turn away from mic, loud clapping or cheering, mumbling, etc.). So...he very well may come with a second head, but I didn't hear it.
I heard TG say they wanted him in his 200X colours so you can take the head of the first MAA, put him on the SMAA body and have your 200X MAA. So, if he DOES have a second head, it won't be the same as the first MAA (by reasonable deduction). So...hopefully we get the ponytail head!
I'm sure TG can clear this up if asked nicely.
