I've normally put X360 at 50-60M. Time to check that...
Sales in 08 = 11.5M
Now, 08 is likely to be the peak, due to the huge holiday. It may start out with a YoY increase early on, but that won't stick in the time it had a price cut in 08.
Still, it shouldn't be a lot behind
~ 10M seems reasonable for 09
Then it is at 38M.
Now it should start dropping seriously (it is its 5th year after all), and sink to 7.5M, then 5 then 3M (or something ala that)
That's 15.5M, leaving the total at 53.5M, and then some minor other sales to put it up at 55M.
Yup, 50-60M remains intact.
