I think next week will be an hour long episode about what the Governor and his cronies have been up to since they left. S those waiting for the Rick/Darryl confrontation will most likely have to wait two weeks.
Sorry to disrupt the talking dead bashing... But I completely agree with Matt. I think next week is (unfortunately) going to be entirely about the Governor. We probably won't see a lot of the prison except maybe or the mini cliff hanger at the end.
