Guys relax, it is ONLY a game, I am sure that in terms of gameplay PES2008 will be excellent, of course I would like to see superb graphics and innovation but in the end if the gameplay is solid that is good enough for me.
As for FIFA 2008 it is clear that they have made great strides this year, they have built upon FIFA 07 and UEFA CL, there are lots of innovations and it remains to be seen how these work in gameplay. The video of the EA presentation where they show the England V Germany match looks good to me and you can see that EA are going in the right direction, it remains to be seen if they can match PES gameplay.
I think both games have their own individual strengths, neither is perfect and in the end it will come down to individual preference. So relax guys it is good thing for gamers that this year it maybe that there are 2 good football games on the market.
