Fellas, Insomniac themselves confirmed the 17 gig size drop due to compression way before the game was launched. I didnt post in here at the time because that was during the "spoonie isn't posting in sony forum because it's all negative"[even though all sony news is negative lately].
Funny how Insomniac were the big supporters of bluray and very vocal about the 360 and its storage problems at E3
