The Launch Date for Splinter Cell Trilogy HD for the PS3 seems to have been pushed back until September 27th 2011. Ubisoft had not offically given an announcement for the award-winning collection of games, but retailers had set the original date for August.
This new date of September 27th comes from 3 major retailers, Gamestop, Amazon, and GameFly (who conveys with publisher provided intel only.)
