Actually a lot of people care for it, they're just not that vocal about it online, on Kingdom Hearts websites. It had one of the biggest cheers during the 2013 E3 conference, and there was some great stuff there that year.Would be great, but that's not going to happen :S
Also, can I just say how nobody except for KH fans seems to care about KH3? I'm looking at all these prediction lists and can never spot KH.
