Notice that for a number of people on the site, Wii is the first Nintendo console, which, atleast to an extent, explains why the Sony characters are comparatively popular. Kind of a same thing with Nintendo characters remaining popular despite Nintendo consoles losing in popularity.
There are also a number of multiconsole owners in the site, and PS3 is the latest of the three that had a big exclusive release (MGS4), while 360 and Wii haven't had anything near the same scale since spring.
Also, you forget the number of Wii Music threads a while ago, which spawned just as much as the LBP threads are at the moment, basically we have threads going about a console that has something happening. Halo release spawned a huge number of Halo 3 threads, GTA4 flooded the forum with GTA4 threads etc.
Also, the race between 360 and PS3 is most likely to lure in people interested in PS360 sales, since there's not much to see in Wii sales (outside how much Wii outsells combined PS360), or would be in relation to DS, if DS wouldn't top Wii sales for 100k per week.
I'm not saying that you would necessarily be wrong, but that's just the regular cycle we have seen quite a number of times already.

Nintendo games sell only on Nintendo system.
