Seems plausible. Then you add ~2.5m for holiday 2013 and you have 12-13m total.
Maybe MS could aim for 15m but that seems roughly ballpark.
Sony aiming for 20m seems reasonable. Roughly 3:2 ratio.
If Sony can increase manufacturing capacity they could do better, considering launching in Japan+ROW.
(especially if they can reduce production costs and do a price drop next holiday, even by $50)
