Realistically square was originally making FF games for nintendo,they jumped ship to sony as many other 3rd parties did when psx was released because the cd format was cheaper to produce then cartridges.Thats how Sony became the leader in software,because nintendo stayed with cartridges.Sony also was open to broad ideas and let alot of games through the gate that nintendos strict policies would'nt have let fly.Anyway right now xbox is the software leader,because dvd is cheaper to produce then blu ray,even though they're not that far of sony in hardware sales,most multiplat games sell better on 360,so unless sony really holds the rights to FF7,you can count on it being multiplat,at this point in the console war nobody is going to neglect the market.These developers are out to make money not be brand faithful.
