I dare say it's a number of reasons - the 'all of the above' option
In my case, I go where the games and tech interests me. PS3 just has more games that attract my attention. There's things to think about in LBP and EOJ that aren't present in Bioshock and Halo, because they're different. The ordinary games, sports and racers and shooters, aren't really doing much of interest worth discussing. KZ2 got my attention because I wanted to see any of that secondary illumination in effect. A lot of the XB360 games aren't claiming to be doing anything new (least not that I hear, and it's hearsay that's educating me what to be interested in!). This is mostly because Sony's 1st party activities are aiming to be diverse.
A larger ratio of European population might have a similar degree of interest to me (??). They'll play Forza and Halo and SportsGame, but there's not much there to
discuss. When EA start showing super-dooper behavioural physics sports animations in their upcoming XB360 exclusive, it'll get interest. As long as that tech is cross-platform, it doesn't count as an XB360 thread. That is, you'd have to look at XB360 exclusive titles and what interests they provide. If they're not doing much out of the ordinary, they're less likely to get discussed. You just don't have anything to actually discuss! If MS were to release something gobsmackingly original, like a gesture controlled origami game, or a racer that's implementing real-time GI, I'm sure it'll get discussion going. That's just not MS's approach though. Though strangely, the 'interesting' titles do seem to get overlooked. No-one's discussing Fable 2, despite it showing some of the most divergent ideas for RPGs.
On the matter of fanboyisms, it's probably true there's more extreme comments made over PS3 games than XB360 (you only need one or two 'enthusiastic' members among thousands to be vocal), and the moment there's any controversial remark, it'll get 'discussed', and that's what really bloats threads. Two people with different interpretations of each other's comments can go on for pages, roping in a few onlookers, pointing out how neither one can read properly (have you noticed it's always the reader's fault, and never someone not writing down their ideas in a way the other can understand? It's always 'you can't read' and never 'I didn't explain myself very well'...), and that's when the thread grows. If you lost that behaviour from the forum, I think PS3 threads wouldn't be so big, but would still have a bigger presence because on the whole they're more interesting in doing new things that are worth inquiring about. Wii just confuses us tech-heads. Push-ups for a
game??? Who wants to buy a $250 console and peripheral to do push-ups?
