I think it's a mistake to have Luke, Leia and Han return as the main characters for the new trilogy. For me, this is a sign that Disney/Lucasfilm lack the guts to take the saga to a new generation. Instead, they are overreacting to the Darth Media's reaction to the PT by trying to rehash the vibe of the OT. Even if the movies become hits . . . from an artistic POV, I believe this is still a big mistake.
