My take on modular data storage would be since games can be 100GB. By being modular you could allow the user to decide if they want to download the multiplayer or the single player story first. Or even the ability to download enough to get the game started and a few levels going. It could mean gamers with a slower internet connection wouldn't feel like they needed a physical copy. It's just the evolution of games going digital I feel in addition to the games getting bigger.
