I don't know if anybody else noticed that, but, here you go, in case someone really needs it.
This couple of weeks I've been tested new stadiums for FIFA 13 and I've noticed an interesting fact. If you don't choose a "clear" weather, the new stadium added will look quite good in the game. The only bad side would be that on the night time you'll see a clear blue sky (or white, depending on the stadium) and the floodlights won't turn on! But if these little details can't bother you while you're playing, then you will enjoy the new stadiums without replacing any default stadium at all!
From all the stadiums that I've tested so far, only the Camp Nou created by BFL Team doesn't have any problems with the "clear" weather. I'm guessing that the respective stadium still has some graphic elements in the game from FIFA 12 (like the previews for example).
