I'm very seriously considering ditching Pathfinder for 5e.
There, I said it.
I could never bring myself to sell my PF rulebook though. And it's unlikely I'll sell my Swords&Wizardry books. There are only two of them, and frankly, they're good enough that I'm still likely to run S&W for an even more casual game.
I only have a few non-primary PF rule books, though I do have a few full adventure paths worth of modules.
The only wrinkle is that I'm currently in love with the Midgard setting, and at the moment, that's only spelled out for Pathfinder. I suspect that until WOTC makes their licensing scheme known, we won't see any 5e Midgard stuff, which would be a shame.
Hopefully the rumored "3e to 5e conversion guide" will help.
Honestly, I'm probably not going to be playing much D&D over the next few months, since our "Supers!" game is going well. I'll blog about our latest session in the near future.
