It seems like they will HAVE to get the SP onto 1 disc. It wasn't a big deal for LA Noire because the swapping was required for faces, not the city. However GTAV won't have the face data, so that means the assets (aka the city) is what is going to take up most of the space. In an open world game you can't have swapping between different city areas.
I'm sure Rockstar will figure it out (They have to).
