Just curious since they were rumored to be 25GB discs (assuming BD-R)...

I don't have the system yet but I'm picking one up here in a few days when stock is available.

I don't care about the actual game dumps, more into the specs of a few launch game discs and what the file format/disc type is, etc.

I do realize it's early but I'm sure someone has at least tried to look at the format.
