Will this ever be possible? I for one would like to install everything to hardisk off the bluray. Space is of no concern.

I totally understand not everyone might have or want to give up another 10-12 gigs. But since its a mandatory 8gb install on the Ps3, why not give option to full install as well?

GT5 has this option.

The 8gb install limit is highly likely to do with pirating precaution. The dl version of Infamous was 7gb or so, same as Assassin's Creed Brotherhood. I don't know how the hell they compressed so much of those games, but they're that small. I'm guessing the 8gb install for Rage, is too, a compressed version of a much larger file much equal to the xbox360 version; just my guess.

I heard the xbox install was optional for the full 22gb over 3 dvds and same as pc dvds. Correct me if i'm wrong.

I know the steam version is 22gb download and 25+ after decrypt.

So if its optional on the xbox, why not give same option on Ps3?

From my understanding, its 8gb on the Ps3 because all the files can fit on the bluray, so game play can be continuous while loading stuff off the disk as and when needed. Not possible on dvd so full install is an option if you don't want to change disks during gameplay.

This has nothing to do with pirating precaution. Sony fixed their epic fail long ago and new games like Rage can't be pirated on the PS3. There a copies on the net, but there is no way to play them with a hacked PS3. Totally useless ^^

The 8GB install of rage is just a partial install from the whole disc. 22GB in total but "only" 8GB get installed, the rest is loaded directly from the disc.
Infamous and Assassin's Creed aren't specially compressed, they simply are only 7-8GB in size. That's a normal size of most games. Not every game needs that much space like rage or L.A. Noire.
The only reason the install of rage is "just" 8 and not 22 is because Sony wouldn't allow it. Most installs on the PS3 are even smaller and it was a nice exception, that rage could have a 8GB install. And id wanted a large installation so they could minimize texture loading.
But a optional full install surly would be nice, although I'm not sure if the game would really benefit that much from it. Texture loading is certainly superior from the HDD than from the disc, but the rest not necessarily that much.

Great, you seem to unequivocally know how Playstation work. Its always good to have a know it all. I was only speculating.

Sorry if my post made a rude impression. English is not my native language.
My post was meant just as a friendly explanation to your post

There's nothing planned at this time. If/when that changes, we'll let folks know.

I don't even think that would help. The Xbox version uninstalled has less pop-in then the PS3 version. Might be a memory issue.

idk if you could.. on wikipedia it said the uncompressed version of this was 1 terabyte...
