I don't know... I don't think Jimmy would bother doing this if he didn't have anything new to offer. Especially since they've actually been involved in the process, I don't think he would let it be something we didn't like or get something new out of. Why else would they participate in it? Of course, you could be right, but it's foolish to judge it before we really have any information on it.
On a side note, everyone seems to be calling this something related to "Jimmy's cleaned up history," but this only goes up to '70. What does he really have whats worth hiding from back then? It must be something pretty top secret if there is one, because I can't think of anything very secretive or scandalous from their early days (Except maybe the mudshark incident, but what do we need to hear about that?).
