I thought they already did something like this. I recall some people complaining because the naive decryption process would double the required hard drive space while the bundle was unpacking on release day.

There is no need for the decryption to double the needed size. You can chunk it to something reasonable and effectively rewrite the file in place.

Pretty sure they already do it. I've also noticed that if you have a fast connection (like 1 Gb/s down), it might be faster to download the game when it releases than it is to preload it and then decrypt it, since the decryption process is quite slow.

Of course they do. GGP has no idea what they are talking about.
