Aizen will definitely be returning sometime this arc. Kubo gave us many hints about this.

However, I seriously doubt that Aizen and Askin are the same person. Their appearances might be similar, but their personalities are just too different for this to be possible. Also, what reason could Aizen have to disguise himself as one of the Sternritter? It was never mentioned anywhere that Aizen has any interest or association with the Quincy.
