Actually I think that's exactly what we'll have to do. They said legacy DLC will become available as it's released as DLC on the current gen systems, so it sounds like they will just start releasing all the old DLC as "new" DLC and if we already purchased it we won't have to pay again. I don't know at what rate they'll release the legacy DLC..I don't think it will be one or two songs at a time, but they did say not everything will be available right away.
It just occurred to me I'm probably gonna need a new HD for my PS4.
