Oh, the data assumes that every console bought last gen was bought by a different person. It neglects not only the possibility that a single person might have bought the same console multiple times (*cough* RROD), but also the possibility that a single person might have bought multiple different consoles.
So, if the average person bought two consoles throughout the generation, then actually closer to 15% have already upgraded to next-gen, right? What if the average person bought three consoles, are we already over 25%?
Very useful data we got there.
