They are showing literally EVERYTHING about their game before release to maximize hype. There will be zero surprises. This happened with ORAS, SM, USUM. Don't fucking trust Pokemon's Marketing Division.

The very fact that this is all they're showing is also proof of how barebones this game is. Leaf? Red? Blue? They'll all be short one-time encounters that you'll get over with and just say "neat" before moving on. The only thing they had going for them was the surprise factor but they ruin it for more sales.

DON'T BE FOOLED AGAIN.
