Reading some of the replies, I'm wondering how much the frequency at which one plays has to do with readiness for change. I'm with those who feel they still have 3E ideas they want to explore. I've never gotten to play an epic game, but I played a warlock to 17th level and was salivating at the epic options. But that was years ago, and since then I haven't really played very often.
I have pretty much all the books for Pathfinder since I just rolled my Dungeon and Dragon subscriptions over to the AP from the get go, and I've dabbled, but I haven't had a group with which to game for years. So I'm still interested in exploring some of the later 3.5 stuff, then delving into PF. But while I'm not ready for a new edition, I'll probably still pick up the core books to check it out. As was previously written, getting older does have the advantage of making money less of an issue, so I'm cool with spending some on the new books.
