With all the trouble over the PSN being down and the news around it you would be forgiven for not knowing that Sony have an announcement for what they describe as a "Gigantic exclusive for PS3"
It will be here aprox 50mins from the time i make this post.
and no it isn't PSN coming back up, its an exclusive title yet unannounced.
If I were a betting man it is one of the titles Square or Kojima has been working on (possibly their collaboration), or the rumored unannounced Rockstar title said to be a PS3 exclusive from as far back as 2007.
dug up the article referring othe the rumored rockstar title
Claims Rockstar had committed to a PS3 exclusive back in 2007 that was not LA Noire (which at the time was also exclusive but since turned multiplatform).
