i read some where that sony has given permission for the rage to be installed on the hd
never knew that had to get permission for the ps3 to install to the hdd, seems abit daft really all the ps3's hvae bigger hdds than the 360 as standard, and you can upgrade them more easy.
should give you an option install 25%/50%/75%/100% of the game etc, most i know that had the 40/60gb ps3s have upgraded the drives
