Before you go adding this stuff, where's the proof?
I found a site where the owner has the beta release of the game, the beta was released as a DS game and he has posted some parts of the history and the gameplay.
Link (the website is in spanish)
P.S Where did you get the names of Shiratori, Killards and Kabuno?
I found those on a Japanese website, those were the only things that I could actually back with proof (As for Killard's name Elzes, it is mentioned that it is in the movie). No offense, but I actually trust a Japanese site more than a Spanish one. If I can't find any mention of that stuff in Japanese, then it's just speculation. I also checked out the Spanish wiki, and I could say that all of the stuff listed there is also speculation. Besides, the fact that those articles were written on 9/20-21/13 is also suspicious to me. Also, why would a Spanish guy have the beta of the game? Normally, Japanese people would have it. And if Japanese people did have it, it would be all over the internet by now. The point is, I don't believe any of it
For the moment, I ask the owner of the site how he has the beta and if all the things that he has posted are true.
I doubt that it's true. If there was a beta release, then it would still be mentioned on Japanese sites.
I saw his reply:
"The information is true, is directly extracted from the 1.02 beta for NDS Inazuma Eleven Future. This blog receives information from employees of Level-5, there is where we get the BETA."
And the fact is, that doesn't prove anything, even I could say that. And the fact that he has Kabuno instead of Kumano on his info, and the main characters' names are incorrect (Japanese sources say otherwise), proves that his info is incorrect. Also, I could find no evidence that a beta 1.02 of Inazuma Eleven Future actually exists, and I wouldn't think Level 5 was the type to release Betas anyway (If they really did release a beta, why would it be for the DS? It should be for the mobile phone). You're just ruining your reputation by adding speculation from sites that are questionable
