How about an attach rate chart?

Quartz said: Pfft. Now that would NOT be easy to do. I personally wouldn't know where to start with regards to this.

Depends what you mean by 'attachment' rate. 1) Some people will have more than one current generation console. 2) You're making data based on sales only. 3) Making data based on sales only does not reflect on what each person is playing the most hence 'attach'. 4) Even if you asked pepole who had 1 console or more, which they played on the most. The chances are they will say 1 console over the other just because they have been playing the latest game on that 1 console recently. Basically I'm saying 'How many hours does one play on a certain console' which would reflect true 'attach rate'. However getting data for that would be almost impossible hence my first reply. Feel free to tell me if I'm going into too much depth here! Phew...
