Wow, those installs/save file allocations are tiny. Though I guess with the games being on cards instead of discs, they can read the data faster and don't need to use as much space for saving.
Still getting the 32GB card that I've paid off, and I may switch some of my pre-orders over to the digital copies. Though it bugs me that it seems to be a straight 10% cut across the board. It should be $5 less for the digital copies, imo. At the least.
