Yes, we haven't seen her full body pose, but I could have an interesting theory about her.
If you look closely, you can't see her belt, and since there was Golden Queen in the opposite place as her, what if this character is a villain? I mean, there's a low chance since we haven't seen her entire pose, but I thought this would be interesting to talk about. I thought this because one, we can't see her belt (just yet) and it would be even, two villains and two regular Sensei Skylanders. I hope this isn't the case though, but it could be.

That's completely possible.

However, let alone the fact she doesn't have a very villain-like design, I think she's a Sensei Skylander because she has the same golden/black armor pieces as the others.
That, along with the golden belt, are the only traits which all Senseis have in common, apparently.

That is a very good point.
We'll just have to wait until she's officially revealed I guess.

Yep.

I hope they will be shown at E3, similarly to how Krypt King and Gearshift were first teased and then properly announced.

Oh yeah! I remember that from Trap Team! I hope that happens again!
