@LeiaOrgana - The only benefit of a disk, is trade-in value. No return at a Gamestop or similar store for a digital copy. But I get where you're coming from.
On topic, there does seem to be a good amount of space on the outside of the Hall that could allow for additional content. I've mentioned before, that I can't imagine that everything for this game will be released before years end with next to nothing for the entire following year.
