Like the Dinosaur coming out of your wall and then also talking about Unity.
We have to remember that when they talked about this it was around a year (or more if it isn't delayed) away from shipping and they talked about it at a developer conference. It was clear that they were focused on the technology it has and the mostly Apple developed experience of it.
I still don't fully understand where the idea that this could not be used for gaming came from, except maybe the lack of (VR) controllers but I can't imagine not being addressed by the Mifi program later down the line.
