Now that it looks like they might really be fleshing out the Core World, I'm changing my vote: I don't think I'll need another D&D campaign setting at all.
I buy into it if it was released with adventure books like Eberron was(though I wasn't super satisfied with those.) Maybe if Paizo released a campaign setting book along with Pathfinder, that'd be really great. Especially if it added mechanics and such.
I homebrew my campaigns, and I usually don't buy campaign settings. I'm far more comfortable using my own imagination than someone else's, I have more control over it, and it costs me less money.
Geez, can't people wait for the polls to be posted? The way the boards are set up, you have to post the thread first, then the poll. It takes a few minutes.
There was no WotC or Paizo option so I couldn't check it.
Since the pantheon and fluff in 4e is really rubbing me the wrong way, if I do buy 4e, I'll get the FR setting. Perhaps they will change some feat names to make them fit FR and include a pantheon with gods not directly devoted to combat and adventuring. (I wouldn't be surprised if they did kill off a lot of the non-combat type FR gods, but I really hope they don't.)
It depends. It would have to be really good, and I probably wouldn't DM it (working on my own, and the gods blurb doesn't sound like a good sign. Nor do dragonfolk or thieving gypsy hobbits on rafts). I could put up with playing in something new, and it would be hard pressed to be worse than Eberron or FR.
