As long as the editor for both, the european and the american versions are the same, and the number of players in the game are the same (PES 2008 problem), I don't see any problem not having enough option files. With the help of compulsion, this could be the best year for option files yet, as american gamers like me would also create option files not only for the american version, but also for the european version, in which case we can work together in making better files where we can share teams and players from different option files.
I just hope konami doesn't screw us over again like the past couple of years, and I also hope that the Nov 11 release date is confirmed, because i've had to wait around 4 more months to get the game since the Winning Eleven 6 (PES2??), and the release date difference would be considerably decreased to a couple of weeks rather than months.
