It’s become a sort of Poke-tradition to have a remake of an older Pokemon game every generation. The GBA and DS did it and the 3DS looks to be no different. When Pokemon X/Y leaked around late September I saw this in-game tease for Ruby and Sapphire remakes but wanted to wait until after the game released to post about it. That way I didn’t spoil this tease for anyone should they stumble on it themselves.
Here are just a few images from Pokemon X/Y that clearly tease a Ruby/Sapphire remake. I don’t know if Game Freak will release a third version of X/Y (Z maybe?) first or these remakes but something is coming. Personally I’m a fan of calling them Royal Ruby and Sacred Sapphire myself. Here’s a warning to you, these images may contain some spoilers.
To be fair other Pokemon games and regions are referenced in X/Y but these Ruby/Sapphire ones are a bit direct.
