I'll be honest, I'm a little suspicious of the 2 disks thing. The game itself is about the same length as the first one. Makes you wonder if EA are pulling a NFS: Carbon on us and charging for content already on the disk.
most of that space is other languages and vids, friend of mine got this as a ripped version with no other languages than english and all vids -50% quality, took only 4-5gigs.
All that audio and texts take a lot of space apparently
