Ichigo said that the fight will be over in an instant, so why the hell did they need to change location anyway? Probably his new powers is atomic bomb or something?
He could have some sort of Quincy-ish new attack that drains reiatsu (or however you spell it) from around him and then produces a Getsuga-type blast. It would give Kubo an out to having Aizen be ridiculously overpowered by simply letting Ichigo drain out all his power and then kill him with it, or something.
That sounds really, really awful, but on the other hand I don't think anyone still has high expectations for this series...
