True: its the whole of Square, not just the USA unit.

Its very unlikely that SquareEnix will stop making FF's for Sony - like the majority of developers now, SE will try and produce for all major consoles [GB+GC+PS+XB]

Its a mistake imo to make seperate games for seperate consoles though, they would do better to have the whole team working on ONE FF at a time and then 'porting it to other consoles instead of diluting the quality by working on 3+ new projects at once...
