If you're not already pumped for Pokémon Omega Ruby & Alpha Sapphire, Nintendo is looking to change that! Frequent news updates have introduced new Mega Evolutions, new gameplay features, and new additions to the established Third Generation storyline. This time around, an article in CoroCoro magazine reveals new details on Primal Kyogre, Rayquaza, and Mega Gallade. Additionally, it looks like some of the content you unlock in the game's demo (so far only announced for Japan) will transfer over to the final game.
Yesterday we learned that Primal Groudon will learn a new move called Cliff's Blade. CoroCoro reveals that Kyogre will counter with a new move called Origin Wave. Details on these moves are not yet known. Meanwhile, the legendary dragon Rayquaza is said to "hold a secret to Mega Evolution." Will he receive a new form himself? Mega Gallade has been revealed as a Psychic/Fighting (still) type with Inner Focus as its special ability.
As for the demo, it's said that "something special" will happen if you play it every day. Perhaps there will be new content added to the demo daily? What we do know is that any items you collect in the demo can be transferred over to the main games when they launch. This includes the Mega Stone you receive at the end of the demo.
