Interesting and good list. Personally I'd add Gears due to release dates but I would leave KA out as you noted.
Pretty much confirms a similar state of affair SW to HW - MS has sold more overall in terms of LTD but time adjusted it's pretty even overall, with a slight lead for MS. The major difference is that MS strategy is around a smaller (comparative to Sony but still fairly large in its own right) number of titles and a very small number of huge sellers.
Sony has a smaller number of huge sellers but pushes out a lot more titles (much the same strategy as with PS2, try for blanket coverage of lots of genres/demographics).
Both approaches have their pros and cons and it's interesting to see they come to such a similar result overall.
One thing though, seeing GT5 at the top of the list and still way below its probable LTD you really have to figure Sony should have worked harder to get that title out earlier in the consoles life.
Really, with HW/SW so similar and a similar feature set across both HD consoles now there's just no point hating on whichever HD console you don't own. Not that the core haters will change their tune now, but really, if you dislike the PS3 or 360 and prefer the other you're basically hating on something that's over 90% identical to the thing you love. But that's deindividualism (amongst other things) for you.
Try to be reasonable... its easier than you think...
