I notice you used the FF12 sales in your analysis.
Lately we've been hearing about how FF13 sales will be far more than FF12 because "the first FF on a new system always sells the most" or something like that.
FF7 and FF10 both sold over half their copies outside of Japan. Combine that with all the other JRPG news on the 360 and I have to agree with starcraft and say you're trying to spin this and lessen the blow.
