Bleach Manga thread (SPOILERS)

Now we barely got any answers here. We don't know what happened to several characters, Who's the new soul king or did the old soul king survive somehow? Why did Aizen voluntarily go back into prison? And I still can't believe the final panel of the entire series, conclusion for all these years is a face saying "Whaa"

I'm making assumptions that the soul king no longer exists, and Aizen's original plan was to kill the soul king. He probably doesn't see a reason in fighting anymore when his original plan has already been executed.
