If it isn't, sure looks like it! Or maybe, just maybe by coincidence I saw these news today! For starters:
Sony announced this sweet pack of all three Assassin's Creed games with Ezio as the main character, properly named Assassin's Creed: Ezio Trilogy. Word has it that it will include all DLCs from Assassin's Creed II as well, but nothing was disclosed about the remaining games' DLCs. It will be released on the 13th of November as a PS3 exclusive.
Can I say I'm happy?
