What is the story for Kingdom Hearts 3

Nomura (the creator of Kingdom Hearts) said in an interview that there will be a KH3 and that it will tie Kingdom Hearts Birth by Sleep, Coded, and 358/2 together. It will most likely be for PS3 and Will most likely be with Sora and friends. Or, I could just give it to you straight w/o links There are 3 games, none of them being KH 3, as kingdom hearts/chain of memories included, is just about sora (and his story is therefore over), as the main one is birth by sleep. This PSP game stars the brand new characters, Ven, Terra, and Aqua, with terra the one you can fight at the end of final mix and/or plus, if you max the game out. The new three had cameos in the hidden KH2 trailer, with them having a vendetta against the preincarnation form of Xehanort, Master Xehanort, with him summoning a stooge to assist him during the intense battle, which is one that King Mickey watches from the sidelines.
Ven, terra, and aqua, are said to be possibly connected/related to the destiny island trio, with sora, riku, and kairi being said, officially to be built upon the elements of air, earth, and water, respectively. Two of the new characters' names, Terra, and aqua, mean earth and water, as well, with Ven being the possible preincarnation of Sora, as ven is darker than sora, and sora being nicer because of the nature of the Kingdom hearts worlds, with light reigning over darkness, thanks to mickey. These are rumors, but very likely rumors.
There are two other games, one about Roxas on the DS, and one about a strange note left in jiminey's journal, which involves a sora clone, with that game being on the mobile phone.
