I agree IGN's quality fluctuates a lot, but I have the same feeling with most US media (and also Eurogamer!).
No laggy/imprecise bulky Kinect on the top of that list? An eyetoy-like device requiring far too much space for most people, hailed by a lot of the US gaming press as the second coming of Jesus...
IGN regarding Kinect/Milo E3 2009: "Even so, the potential for this game and how you could ultimately interact with the character is very high, and I'm excited to see where it goes next. "
If Halo 3 was a 9.5/10 (a short repetitive not-really-a-challenge campaign with mediocre technicals, pushing a lot of people to pay extra to play online and pushed fans to advertise Live for Microsoft to their gaming friends to uppen its value) for them I can't imagine Gran Turismo 5 getting anything less than a 11 out of 10! It's simply the best and most impressive racing sim out there, second to none with a big gap in between.
Although I am more of an arcade racer and thus had more anticipation for Motorstorm: Apocalyse, I have to provide credit where due. Gran Turismo 5 as a whole is a true masterpiece achievement, unlikely to be bettered until the release of Gran Turismo 6!
