This is all sort-of irrelevant. What are trying to measure anyway? What do these numbers matter?
- measure company (division) profit - that is a pretty good indicator of things
- measure games sold - that is a great indicator. Usually people who buy games actually play them :)
- measure total units shipped - indicates how many are being manufactured/sold by console makers
...
People buy consoles for lots of reasons. Presents, replacements, first console, media centre, etc.
I think a great indicator is "Number of people CURRENTLY USING a console (i.e. within a week period)" - but that's impossible to measure, outside of game sales.
Does it really matter is 80% of PS2 owners never use there consoles anymore? Anyone ever wonder why game sales GO DOWN as the total install base for a console GOES UP? (look at long-term PS2 sales in Japan - strongest game sales were at launch!).
