The Sly Collection, a remastered port of the Sly Cooper trilogy currently available only for PlayStation 3, has been rated by the ESRB for PlayStation Vita.
Released in 2010 and again in 2011 as a digital download, The Sly Collection includes Sly Cooper and the Thievius Racoonus, Sly 2: Band of Thieves and Sly 3: Honor Among Thieves. The remastered version of each game includes a graphical overhaul and trophies. ESRB rated the collection "E" and provides little other information.
We've contacted Sony for comment and will update accordingly. The latest Sly Cooper title, Thieves in Time, was released for both PlayStation 3 and PlayStation Vita when it launched earlier this year.
