Kingdom Hearts 4?

So I was reading an article awhile back (I forget where) but it hinted that after 3D, KH3 will simply be about bringing all the heroes together (Sora, Riku, Kairi, Ventus, Terra, Aqua) and catching everyone up on the problem at hand (telling the original 3 about xehanort and such) while catching the BBS squad up on current events. Afterwards, there would be a fourth and final game that had the final battle and (hopefully!) answers all the questions. Can anyone else confirm this? EDIT: The only reason I found this believable was because of (SPOILERS!) after the secret BBS ending all it says is "reconnect", which would then confirm that the next major installment would bring EVERYONE together. Now that's not to say that they couldn't have the final battle immediately after everyone is introduced to each other, but I feel like to really flesh out all the character's connections, a Kingdom Hearts 4 seems very plausible.
