Now, Hear me out. It would make sense for KH3D since the plot seems to stem off where KH Re:Coded left off (just so you know Re: Coded may have been one of those random out of nowhere titles but it did come after KH2 non the less) If it isnt 3 then its atleast the next in the series just before KH3 since from what I can tell from the WHOLE 1 Trailer SE gave us about 3 it must be some kind of war or something (im not that much into KH ) But this is all pure speculation.
