I'm wondering if there's something we can do to show people that these trailer impressions have been received and translated to prevent others from bringing it up again and again? The fact that it's shown at the beginning of the thread (and I'd imagine that it's also on the front page) doesn't seem to be helping. Maybe we should make a quick thread letting people know that we have it already.
As for my new quick theory, I have a couple ideas in mind to correlate to what we've been told along with others' theories.
I've been thinking about the whole 'blizzard vs any other spell' enigma. Now, this could be complete BS and too Sci-fi-influenced, but I'm wondering if the freezing allowed Ven to be preserved and kept alive. I'm also wondering why else we've been shown that he was frozen, but still alive in the original secret movie, and that he was recovered and brought to CO afterwords from the trailer impressions. As someone mentioned before, Master Sakaguchi could be referring to the newly transformed Xehanort (formerly known as Terra) and he may attempt to fight him. With that in mind, perhaps Aqua escapes to bring Ven to a secret place where Xehanort could never find him, the chamber of Waking in CO. If she is unable to retrieve Ven, his preserved body without a heart would remain in this chamber for years to come.
