I think the quote isn't really what he means. Here's why.
The whole quote requires added context added by the writer to lead us to think he's talking about Expedition Everest. I think he's talking about a generic coaster and the choice of India was poor as it lined up with an offering the parks had already*. So yes the MO from here on out is exactly what we think it'll be: character based additions to ground the parks. Problem is it's the non-movie or TV show based attractions that also receive such praise and waits to this day, like BTMR, HM, Space, Soarin, and more.
*This also says a lot about how he views the park if one of the headliner attractions in a park that just received $1bn in investments.
