Two Theories....

Which are really horrible, but it will give us something to talk about yea?

First theory, I think KH3D takes place as Sora is sleeping. What?! Yea I said it, why? Because 1) We already know what he was doing from KH1-KH2. So how does this all fit in? Well he was dreaming the whole thing of course. I mean there is no where else to fit this story if you look at it. And it is really impossible for it to happen before KH1, seeing on how Sora didn't get a keyblade till KH1.(unless nomura does some kind of twisty thingy, which he is known for). On top of that he fights a Twilight Thorn, I'm thinking that whatever Roxas went through while Sora was sleeping, is what Sora dreamed. like when Roxas had dreams of Sora's past adventure. Thats all I really have at the moment.

Second theory, This could have happened prior KH1. Where some how they both got keyblades and used them, and at the end of the game there brains get erased and nothing ever happend <-- Got lazy and didn't feel like typing so i went straight to the point.

 

*spoiler* do not read on or die.
they already found Ventus' heart. They are looking for Terra's now. To be exact I like the idea that it will be the test of master, but i'm just not so sure. On top of that Master Xehanort and Vanitas will be making a return, I do believe, but then again I've said this for about a year now.
