I'd be surprised if this area didn't have virtual queues. I would think Fallon would be them testing what works to replace pre-shows. I mean, with Nintendo, why wouldn't they want to let people explore gaming in a room for 20 minutes, then move that group to another room for 20 minutes of play...and then on to the ride.
Yeah, using the queues as pre-shows and letting people play Nintendo's latest and greatest games and consoles not only improves the queue experience, but helps promote and sell Nintendo products.
