Is That An All New Look For The Beast? (Potential All New X-Men Spoilers)

In the curent All New X-Men comic, we have a very poorly Beast. And a Beast from the past trying to help cure him.

Does he succeed?

In this preview of All New X-Men #6 posted by iFanboy, we see the X-Men in the school dining room.

The table nearest us has the pupils of the Jean Grey School For Higher Learning. The other table has the earlier version of Iceman and The Beast sitting on it… with someone inbetween them. Blue and furry. But with a very different look. A new character? Or a new Beast, talking to his younger self?

Does anyone recognise those leggings?
