What's I'm shocked that no one is really talking is the fact that it takes 25 minutes to install a game before you can start playing it (Installing 40-50ishGB games from Blu-ray that only need to have half of the game installed to start will NEVER take less than 15-20 minutes)
Remember when when people were bitching about the PS3 installs?
From what I've gathered the PS4 doesn't require any mandatory installation of game prior to starting as it does it all on the fly....
I installed all my 360 games. I don't think it's an issue.
