the problem for square is that it's hard to launch a new popular rpg series
and rpgs are what they are good at
sony's got many studies doing al kind of genre's for years, where squares got mostly rpg teams, with many members that have mostly developed those kind of games
and besides final fantasy, no other rpg, except DQ in Japan, is big worldwide
so it's not so easy for them to come up with new money making ip's like it is for nintendo sony, or konami, or capcom or ms
