I'm not sure I buy India coming to Epcot. Much like with an African pavilion that was in the works, India, while not specifically mentioned there, is already well represented in Animal Kingdom in the Asian / Anadapour area. I think Brazil is much, much more likely.
And can we all agree that WDWNT rumor record is maybe 10-20% accurate? They get some right, but do so buy just throwing a ton of stuff at the internet wall and occasionally something they say sticks, but mostly its about click-bait for them.
Interesting analysis - it basically says that TSL did nothing to drive people to DHS.
But the question still remains of whether it was really meant to or not. SW is what is being used to drive people to DHS.
TSL (and Mickey's Railroad and Cars show as well) are really there to occupy the crowds and bring the park up to a full day experience that it almost never was, and with the removal of backlot tour, LMA, and GMR which were all LONG rides - definitely this park is not an all-day park. For all of SW lands expected popularity - people are unlikely to be able to spend the entire day there, unless it's standing in 5 hour lines. (And I still very much suspect Disney is going to do something very revolutionary and eliminate the standby line completely.) TSL also gives people with smaller children a reason to come to this park, which outside of Disney Junior and a couple of stageshows and M&G is not really well designed for Disney's base.
So - has TSL driven attendance? No.
Is it a success for what it is intended? I think yes.
