Sorry for missing recent news, maybe this topic was discussed, couldn't find anything.

So, according to this article, GTA V will be released on 2 discs for Xbox 360. Up until now we're good, we can just iso2god both of them and gg, right? WRONG!
Apparently, the first disc will feature a mandatory 8GB install, while the game will be played entirely off of the second disc.
Now how would the FSD multidisc plug-in handle that? I'm just a bit worried, that's all.
