Assuming they do a lot with floats and costumed Pokemon like USJ has, I hope they keep that over in USF. Those walk around Poke costumes look so stupid and won't help with immersion in the land. I hope any meet and greets in the IOA land are handled like Toothless or the baby dinos in JP where they are more realistic and characters are to scale. I'd rather have trainers/professors holding a small Pikachu rather than a 7ft tall goofy looking costumed Pikachu running around the land.
100%. Telling someone who knows nothing about the IP to walk around and hold this ball up to the statues of creatures hidden throughout the land to 'catch' them while linked to the app is much simpler than teaching them about catching, leveling up, different attacks they learn, typing/strengths/weaknesses, and battling mechanics.
