>>35439717People would say that this pic is real, because the merchandising they're showing are too similar to this photo, so it's supposed to be real at this point, so they think that this is a test-demo, where they're testing the assets and feature of the new games, so this isn't the graphic of the game.
But my theory is this: it's all made by pixelpar, and he unironically knows something. First we read something by pokéjungle, then pixelpar shows to us this photo, which is the same described py pokéjungle, so they're related somehow. Pixelpar made this pic by himself or by someone who he knows for him. In this way Pixelpar can tell us some new feature about the new games, without showing the game itself, proved by the merchandising that he maybe already knows the existance of them.
