In regard to the above, there is a "Search Thread" link in the upper right top of each page where you can input like a game ID and so on to search... the search is basically vBulletin's so not sure how we can improve on it, the only tip I can offer is to make sure the search terms are greater than 3 characters long or it won't return proper results.
Whenever I can't find something using vB's search here, I go to Google and do a: site: ps3news.com searchterm and it usually works.
As for having a dedicated Sticky thread with a nice table list or something, that sounds great but getting someone to maintain it is the hard part.. timewise it's beyond what we can do (myself and CJPC) so members would have to volunteer and then we could make you "Editors" to keep it updated based on the discussion in this thread and so on.
Man where was you when Crysis 2 and Killzone 3 got leaked weeks before it was in the store? Hell I remember finishing Crysis 2 before it was officially released! Was funny as heck walked into Walmart and was looking at the games, the girl walked over and said we just but Crysis 2 on the shelve. I looked at her and said "Honey I finished that a week ago." You should have seen her face, was priceless.
