Going by Insomniac's track record this game will release at the end of the year to go with the 1 game a year rule. It's the last in the Future trilogy so with that said predict lifetime sales for the game. For reference Tools of Destruction sold 1.47 million however it was during a time where good PS3 games were few and far between.
Personally I think it will do well to match TOD numbers with 1.6 million LTD being my guess.
