Yeah I think they'll definitely be in AoS until at least the winter finale probably, if not the whole season the new show has only just been green lit, so it'll probably take a while before they even start shooting, and I think the best guess is that it'll air maybe as a summer show next year? That would be awesome, if we'll have Agent Carter to tide us over in the winter, and then the new show to tide us over in the summer... one can only hope or maybe it'll air alongside AoS season 4! (Or MAYBE alongside AoS s3b, if they are really ambitious and start soon) But either way, I think it's safe to say Bobbi and Hunter aren't leaving just yet, but it is likely they'll start setting up the new show in AoS at some point.
