>>37920088Looks like it could have been made by a skilled 3D artist with assets from the 3DS games upscaled, but the style eerily matches the current aesthetics of pokemon and it's a shitload of effort to go to. You'd have to model, texture, rig (unless it uses cutiefly's rig, which it might by the looks of it), and animate it and then fuck around with game stuff that's out of my area of expertise. I'm more inclined to believe somebody got a clip of it, either from development or perhaps editing an upcoming trailer, than I am to believe somebody put that much work into a fake leak.
TL;DR Occam's razor tells me it's probably a real clip, but that intuition been wrong before.
