I kinda expected it to be honest. I mean they did remake Johto like 3 or 4 years ago. Anyways there's currently no information about this new game except for what the box looks like.
They said it was gameplay... prepare to be disappointed. "gameplay"
The title isn't official, posted by third party. I'm pretty sure the official video just called it a "sneak peek". Still you can kinda expect what it will be like, basically looks like X and Y graphics. My only question is if the world will be 2D or 3D.
