I've heard people say for whatever technical reason it can't be made on PS3 the lighting or maybe PS3 can't put the images on the walls as well (although I think I saw something maybe not as elaborate but similar in Assassin's Creed 2 which was demoed on PS3).
However, I personally think Splinter Cell: Conviction will appear on PS3 sometime in 2010 much as the original Splinter Cell was a timed exclusive for the first xbox.
