We actually considered the option to allow Brink to be installed to a PS3 HDD and even tried it here locally in our development environment, but we didn’t see any significant gain from it.
The reason for this is that on the PS3 Brink will use the hard disk cache, which is a part of the hard disk that’s reserved for games to freely write to and read from. As the game progresses all the important files are copied here and from then on read from the hard disk instead of the Blu-ray. This works out to be the same as installing the game, but rather than having you wait until it’s done installing you can jump straight into the game. After playing the game for a little bit there is no noticeable difference between installing and caching because they both run from the hard disk effectively.
The Xbox 360 has support for a similar form of caching, but bear in mind that you will need a hard disk for this. We also recommend to install on the Xbox 360 because the cache is essentially cleared every time Brink starts, so it will need to do the copying every time.
As for the cut-scenes in particular, we can’t prerender those because your character is in them.
