I think it is real. Possibly because when I was at worlds; I was outside talking with Belle (the pikachu cosplayer) we saw two PUI reps(Belle and I were guessing they might have been president or VP, or VIP's; well something like that) because they came in with Pokemon themed luggage bags; including two custom Pikachu golf bags ... (well that and the fact that they were dressed in suit and tie gave us that impression as well)
A pokemon golf ball ... I see it being a good possibility that it is indeed real.
