I don't think you need the pull of the franchise, especially in the case of DAK, for people to go to that park. Guests and fans (well fans mostly) are just kinda desperate right now for anything and they'll still come out in droves for Avatar. It will be something new and shiny and that's all that matters to some. While I doubt Disney will see a spike in merchandising, unless there are a LOT of closet Avatar lovers out there, I think they'll have to see an attendance increase for DAK. Even a small increase will invariably confirm TDO's decision in their echo chamber. It's the very definition of epistemic closure. I agree it still makes absolutely no sense to just have this mini land after almost two years after the initial announcement, but that's TDO in a nutshell.
