What do Conduit/KZ2 have in common? Both suffered due to focus on graphics

i was under the impression that they would be adding splitscreen to killzone 2 via a patch. i dont have any links (my brother said he read it somewhere on the interwebz), but hope they do. id love to play co-op with my bro when he picks kz2 up. the game looks insane.
