This just seems like an overall terrible idea. DAK (and DHS) need a lot more attraction capacity. DAK should have dinosaurs represented. IJ and archaeology doesn't fit the theme of DAK. There's nothing wrong with Dinosaur that a good rehab wouldn't totally fix.
I really can't even see the logic here. Not when you have an area at DHS that is just screaming for improvement and the park needs more rides and Indiana Jones would be ideally fitting given the new direction of the park.
Hell, plop down IJA in the expansion plot at MK's Adventureland if you are just determined to bring it to WDW and aren't going to put it in DHS.
Anyway, I'm holding out hope that this is a premature claim until confirmed by others. Also, the smallest silver lining is that
@Disneyhead'71 IIRC suggested that he was impressed by the DAK plans for IJ so maybe it will at least be good even if a horrible fit.
Side thought: would this development have anything to do with Club 33 in DAK?
