AND we just can't know PSN sales
Sure (well we all know BBS did well in Japan, but not quite as good as KH1/KH2 despite being pretty much the same as a main title), but both KH and FF are international games (and Agito is a XIII game, not Crystal Chronicles or another spinoff). Seeing them not do well outside of Japan is...not good. PSN sales are going to add sales, sure, but not as much as retail. If they bomb at retail, PSN sales won't help them.
