To be quite perfectly honest, I gotta say that I don't think the series will be able to finish this arc in the remaining eps. With the addition of the movie, maybe.

It's more than clear that there will be a second season, but in 10 more eps, I don't think they're going to cover what's still out there. Aizen's murder and the letter that shocked Hinamori (forgotten), Ishida and Orihime (apparently the next eps or two), Ichigo's training (that will probably take some time), other things I won't/can't talk about, etc. At least they're not cutting anything out.

If I look like an idiot, so what. At least I made my point by providing information backing up the same idea.
