It was believed that Splinter Cell: Conviction would only appear on the 360 console as well as the PC; however, a major United Kingdom retailer, GAME has alleged that the game is set for a simultaneous release on the PlayStation 3 as well.
The title was presumed to be released in early 2008. GAME has said the title will hit their shelves on April 1st, 2008 and will include the PS3 with it. Sometimes retailers get info before the world and they let it slip. Something similar happened recently with Metal Gear Solid 4 and the supposed demo coming in February.
Ubisoft has stated that a PS3 version nor a release date has been set. We’ll try to stay on top of this to find out if it is true or not.
UPDATED:
Ubisoft has issued a statement to videogamer.com confirming that the game is NOT heading to PlayStation 3:
"This is just a mistake by the retailer. The game is not coming out on PS3 nor is it coming out on April 1. We’re sticking to the original announcement"
