I don't know if it counts as more data points, but I had a friend who worked in a record store (what's the current term?) who was scarily good at predicting when movie soundtracks would hit the discount bin. :)

What impresses me most is the 'cottage industries' that are developing around the game. Stores with signs 'Pokemon inside for customers only', mental health therapists are seeing improvements, animal shelters are getting more dog walkers, neighborhood watches have more people on the street, people are losing weight, people are learning metric, odd job folk are now offering Pokemon rides, e.g. "I'll drive, you catch 'em all."
