how many discs do you think konami produce for the total for the xbox, ps3, (ps2?) and pc ? i dunno how it works tbh, but i was always under the impression that anytime a new pro is out its not up to date transfere wise cause say konami do want to wait until 1st of september to put the pes discs into production, that could lead in a delay for us to getting the game, say till november, giving fifa that extra edge wouldn't be wise. not everyone has the money to buy both games and most people new to either game would prolly pick up whichever game is out first
i am speculating though
