Assassins creed 3 tried to mimic asylum's style. Its got its differences but it's relatively similar.
Mimic asylum's style? What?
I think AC3 tried to "copy" its previous games styles.. Which dates back to the first one being in 2007.. Didn't Asylum come out in 2009?
I'm pretty sure the AC3 developers have said they wanted their combat to be more similar to arkham's in terms of style, flow and presentation, but you're right this formula has been around since AC2 I believe.
