We like the game so god-damned much we can't wait for November is the reason why we are playing WE7 now. Plus since it will be virtually the same game, when we all get PES3, the players of WE7 will already be great at it and kick the asses of those who never tried it.
Plus it's a good thing to play WE7 as it's great preparation for the national PES3 competition that will take place when PES3 is about to be released. PES3 will be SO different to PES2 in gameplay that all only-PES-players will be lost.
I reckon the new champ, if there is someone better than the current champ, David S of Leyton, London (I've played against his older brother dontcha know!!) will be someone who played on WE7 first.
