Yeah it being really Over-Hyped and I think the reason why is cause such little info on it. So When people make theories they want to see if there theory is correct. I also hate how a lot of people think it the best KH game yet when there is very little info and the game is not out yet.
They're not saying it IS the best KH game.
They're saying it's LOOKING like it is GOING to be the best KH game.
Using confirmed information, and personal opinion, people are saying they think it just may be the best KH game.
Then again, SE has 4/5 KH games under their belt, all with each of their own mistakes. I'm sure they don't want to pull another KH2, so they're being extra careful, and putting detail into this game. So it could be.
