For people asking, if a reviewer rates in average EVERY 360 exclusive game 10 points higher relative to meta than EVERY PS3 exclusive relative to meta, then yeah, of course he's biased.
Maths say they are. A random deviation (no bias) couldn't occur on such a big number of reviews. And it wouldn't be so huge. That's like winning at lottery far too often.
No other website / reviewer exhibits such big deviation.
Edge is mathematically biased towards 360 (10 points in average, that's huge).
