KH3 started development in 2013, not 2006.
The KH series still has a sizeable fanbase, I don't know which gaming forums you visited but on big forums like Gaf and Gamefaqs there's a lot of anticipation for KH3, also there are many KH fan sites (KH13, KH insider).
The game will sell greatly as long as Square markets it well. They can easily use the Disney appeal to get a lot of new people on board of the KH series. Many kids would love to play with their heroes from their favorite Disney movies, like Big Hero 6, Tangled, Frozen and many other big movies.
