We actually know quite a bit about KH3.
We know Sora is going to revive Roxas/Xion/Namine
We know Sora is going to save Aqua/Ansem
We know Aqua is going to save Ven
We know 7 lights are going to fight the 13 darkness
WE KNOW THE VIDEO YOU POSTED HAS NOTHING TO DO WITH KH3.
Except that the HD remake has nothing to do with the development of KH3 and is not hindering at all seeing as how 2 totally different teams are working on each title.
It's one thing to be pissed we still don't have KH3. It's another thing to just have baseless facts and run with them.
EVERY GAME AFTER KH2 HAS NOTHING TO DO WITH THE DEVELOPMENT OF KH3. The "Main" Kingdom hearts team which were responsible for KH1 and KH2 only worked on those 2 kh games and thats it. Re:CoM,358/2days/BBS and Dream Drop Distance was all made by the "osaka" KH team.
The "Main" KH team is currently working on FFVS13. And until thats done KH3 will not begin development. So to counter this they allow the osaka team to continue making KH games since it's either those or no KH at all until FFVS13. Nomura has said time and time again he wants no one touching KH3 besides the main KH team.
With that said Dream Drop Distance provides tons of info on where the series is heading to and whats going to go down in KH3 once it's finally here.
Take your cape off you punk ass faggit. Them nikkas aint paying you.
