The PathFinder folks have made it pretty clear they do not like Epic rules. I won't go into their reasons, however, they are coming out with a new product that addresses high level play called "Mythic Adventures". I'm not sure exactly what it is, but it seems like another even larger jump in power for PCs and is their answer to Epic play as far as I can tell. Maybe a Mythic Adventures playtester will jump in here and set me straight or give a more complete answer.
