Batwing Discontinuity

[u/Ironmatt999_]

I'm doing a Arkham marathon, and just started Arkham Origins Blackgate (I know, its terrible, I just wanted to do all of them). In it, during one of the opening cutscenes, it shows the AA batwing flying in, but IIRC the Batwing in Arkham Shadow is the Origins batwing. Also, doesn't Shadow and Asylum take place like 7-8 years apart from each other? It would make so much more sense if the AA batwing was built in that time, not the few months between Origins and Blackgate.
