Yes i have im just speculating an idea here. may be VAT's master had something to do with the keyblades being there. or maybe he/she knows something about it. I mean take a look at my signature video clip, do you honestly think that the keyblades just ended up there? maybe it has something to do with the history of sunset horizens?
If you're assuming its canon, it's fine to speculate. I just want to point out that it's kinda hard to come up with a plausible idea, since there's just not enough information out there for it to be remotely true. That maybe different when the game comes out, but I think speculating now is kinda pointless. Especially on something that appears to just be a concept right now. We don't even know if it's included in the game.
And to royaljminnis, if the story of BBS was finished after COM was released, why didn't Nomura have an idea who the soldiers were when asked about the KH2 secret movie? Or are you talking about Re: COM? Because if that's the case we're talking about the same thing.
Quoted from American Heritage Dictionary
sym·bol·ism (sĭm'bə-lĭz'əm) Pronunciation Key
n.
1. The practice of representing things by means of symbols or of attributing symbolic meanings or significance to objects, events, or relationships.
Has nothing to do with interpretation. Symbolism is assigned by the creator, not the audience. Interpretation is done by the audience. Meaning you can't just say there is symbolism that isn't there. The only symbolism shown in the video is VAT picking up MRS's keyblades. That means there is an implied connection between MRS(Mickey, Riku, Sora) and VAT(Ven, Aqua, Terra). Not SRK and VAT. So could you PLEASE point out what part of the video gives ANY symbolism for this.
con⋅cept
/ˈkɒnsɛpt/ Show Spelled Pronunciation [kon-sept] Show IPA Pronunciation
–noun
1. a general notion or idea; conception.
Does not necessarily mean the idea has come to fruition yet. A concept is just that, an idea. Meaning that since the KH2 secret ending is a concept video it MAY or MAY NOT have a direct effect on the game. And with what we've been shown so far, evidence points to the latter.
