The conclusion to this weeks episode made me very happy. Spoiler: I really like good Nina Sharp and I was afraid they were going to retcon that and have her behind David Robert Jones plans in the gold reality and originally also in the blue reality.
Also just from the amount of people posting here this season I'd say no one is watching Fringe anymore and I'd be surprised if it's not cancelled. Hopefully they can get at least one more season with another network.
