If the train continues I don’t see how they’d abandon a 5x production cost gross ticket sales model. Of course produce a stinker or two and you might see a regroup.
I think with the capital outlay that Disney is doing at WDW and DL for SWL, they’d want this train to chug along for as long as possible.
I’m sure they are banking on similar success with Pandora riding the wave of new Avatar flicks.
