In one of the following expansions, we are introduced to a planet full of Heartless and must cleanse it or harness their darkside energy.

Regardless to what you believe Disney is, they're not a stupid company. Infact, they're one the most successful in the world
. They know better than to invest 4.01 Billion dollars
into a project and then crash it into the ground and ruin the series completely.
Look at what they did with Marvel. Without Disney, there would be no Avengers Movie, no Thor, and no Iron Man movies. They only simply brought more fame to the series and brought more money into them.
Disney is a good thing.
Get over it.
