No I think Aizen will be overcome by the Hogyoku, but not killed. From a writer's POV, you'd want to keep some connection between the arcs so I'm guessing that Hogyaizen will become a temporary antagonist at least until Aizen recovers his personality. So then it'd be new plans, new characters all leading to a new arc, while still maintaining connectivity.

The 'short arc' could be like a canonic filler* between FKTA and the upcoming 'long arc'. Also, we already have this arc's deadline approaching. Thus, I'm pretty sure Aizen's not going to die as yet.


 * By canonic filler, I mean something that Kubo comes up with to fill in the gaps the the story so far (e.g. Gin's story). I know that Kishi wants to do one on Naruto's Dad so there's that possibility too.
