The season pass isn't mentioned but it doesn't mean the game wouldn't get DLC as single packs anyhow--Injustice was the same way.    Usually they don't sell the Season pass on WII U because that would lock the developers into a "contract".  This way if ACIV sells well enough then the DLC can be added afterwords.

Awww, I was gonna jump in this thread and yell SURPRISE!!!

but ymee took that opportunity away.

But some would argue that it shouldn't be necessary to do that sort of thing.

and then some will go on a nintendoomed rant over the whole thing

"Wii U will be discontinued next week! Glad I never bought one!" /ian
