Anyone with an existing sub will see no change in what they have access to, nor what they gain permanent ownership of (that is: EVERYTHING Fantasy).
New subscribers now make a choice about what is important for them, but even then - both D&D and Pathfinder Fantasy subs gain ACCESS to everything Fantasy.
In addition to this:
D&D subs gain ownership of all D&D AND Generic Fantasy Content
Pathfinder subs gain ownership of all Pathfinder AND Generic Fantasy Content.
