The whole "Cross Breeding" sounds kinda fake but the info about Xerneas' and Yveltal's typings...I don't know...
Same goes for the starter evos...their "appearance" so similar and had a connection to that leaked "names" that came around last week, the whole 'Chespear, Fernox and Froabanet', though I find the Chespin wearing chestnut armour line to be weird.
And the "list of new Pokemon", one of them is a japanese folklore umbrella ghost pokemon? I did speculate a kasa obake pokemon to be in this gen like 2 weeks ago, didn't expect it to be in this rumoured list.

People are gullible if they believe this much information would be leaked ten months before the game is released.
I'm not saying I believe this "leak", because I don't, but this is kind of uncharted territory for pokemon fans. Due to the global release, I'd think that they are actually fairly far ahead, if not close to done, with the core game because of how much time it takes to do the localizations for each region. Plus, more people having their hands on information means a higher chance that something true might actually come out early.
Again, not saying that anything we have seen so far outside of official sources is true, but you never know what can happen.
