It just doesn't make sense that so many activities,armor, dialogue and the world good fit on a single disc. Can someone please provide insight on how would they go by doing this or if they will most likely have to cut stuff pre-release?
If your reason for scepticism, is based on JRPGs (usually they have multiple discs), it's because, they're full of CGI cutscenes. Most western games don't use CGI and some have very few cutscenes.
