The guy needs to put his money where his mouth is.
If the xbox is the only place for gamers, why is their 360 support so abysmal? Why doesn't he try putting DQ10 or FF13 on the 360 with its supposed awesome attach rate? Because even if he gets 100% attach rate in Japan, it'll still be a fraction of the sales potential putting it on another system.
Attach rates can make up for install base only so far. Eventually, a low attach rate with a much higher install base will sell much more. And if he's truly committed to his argument, I don't expect him to ever make a PSP game since that is beyond far the worst attach rate gaming system out there.
