I'm just going to point out the top 10 viewed games in the link below
http://vgchartz.com/games/
obviously at least 1 sony fan (obviously there is 1 ninty and ms fan too) that doesn't have a life and likes to mess with the site. He probably has more time than anyone else. Maybe it is more than 1, maybe not. But most of them shot from ~10k views to a few 100k in a day or two. Its not that hard to defeat the voting system either.
Now, I do agree that there are more Sony fans than before, but I still think the Nintendo fans outnumber them by a fairly large margin, but they aren't as vocal. So we might have 10 (making up number) vocal Sony fans, and 10 vocal nintendo fans, but if you count the lurkers too, then Nintendo would have a much larger base.
