I'm asking because I just browsed ebay and I've seen listings for both a 2-disc version and a 4-disc version and I can't find any info about this. Not all the 2-disc listings look like just cases of someone losing discs either as I see a jewelcase release.

At the moment I'm unsure about actually buying the game (I kinda have to save money) but I would like to be informed when and if the time comes.
