A document was recently "leaked" which lists Pokkén Fighters being available as a demo at the upcoming E3 event.
This of course could definitely be fake so be aware!

Unless what you have is confirmed to be true and you know it to be this is speculation.
Speculation is against the rules.
I'd advise reading said rules.
You linked to the wrong article and also, there's no reason to believe the image.
