I have noticed a drop since about 8 months ago, both here and on HTS. I think it might have something to do with the lack of passion that was present when Gamecube/XBOX were being released (and shortly after). At that time, people couldn't shutup. Maybe now people are just playing the games more and talking about them less. Systems Wars threads seem to be going away simply because everyone on these forums owns between 2-3 next gen systems now, whereas two years ago people owned just one. But that doesn't mean the PS2 s#cks any less. Just that people are tired of talking about it
