A few more rumours floating around that seemed interesting, so I'm gonna post them. (Feel free to do the same
-164 Pokémon during the main game's Pokédex. Total of 813. 3 secret, #810-813.
-Gym Leaders of Poison, Steel, Fighting, Ground.
-Non-linear gameplay path differing by version. Begin in same town but follow different route to the end.
-Major area, new Cycling Road. Based on Tour de France.
-Villain team, "Team Helix." Military themed. Leader is female, Colonel Zenia. Wish to capture Xerneas/Yveltal to make their Pokémon stronger to conquer region.
-Professor is also female, Professor Yew. Dr. Eibe in Japanese. Very European in appearance.
-Xerneas, Normal type, found at Origin Tree. Yveltal, Flying type, found at Needle of the Sky. Both have ability, "Gene Donor," changes type to one of their moves. Between them, all TMs can be learned.
-Divene Region, very, very massive. Map is confusing.
A few of these seem like they could happen, (ie. Professor Yew, which follows in the trend of the Tree named Professors. Oak, Elm, Birch, Rowan & Juniper for those who can't remember.)
Different Route idea is a rip from Black & White / Black 2 & White 2.
A confusing map (If true) would be fantastic!! Getting lost constantly will be fun if there is a fair bit of random caves, lakes and more of those Hidden Grotto's from B2/W2 and the whole Tour de France idea would be fairly interesting to see.
Seems interesting, but I doubt that X&Y will have most of this in them and they'll soon just be debunked by Nintendo like usual.. Whatever way though, they need to release more info about the new gens real soon. Getting bored of them just releasing more Passwords to their other games.. *grumble grumble*
