The only issue I'm having is I can tell that both my group and I are going to want to play some more fantasy even after this wraps up. I'm not going back to 4th Ed, no offense to those that like it I hope you continue to enjoy. And I got rid of most of my 3rd Ed/3.5 material some time ago. Since actual D&D Next won't be available I guess I'll either need to turn to my non TSR/WOTC rpgs or I could pick up Pathfinder (I have the Beginner Box but nothing else). Pathfinder is a hard sell to my groups though. There are some who don't want to "go back to 3rd ed" as they see it.
The problem is that Pathfinder IS 3rd ed. It's a 3.55 variant, and it's got ALL the same mechanics as 3rd ed, with a couple of tweaks, so yes, they are not likely to switch to PFRPG because they correctly view it as 3rd. Now, if your players were cool with playing 3e, then yes, you'd have no issues, but honestly, I think you're SOL on getting them to try it at the moment.
Personally, I like most of the editions of D&D, although I am burnt out on 3.x. I will freely and happily admit that PFRPG has some great changes to the mechanics (even if it invalidates most of my 3.x library in the process, but hey, they have to sell books too!) But for now, I'm willing to see what D&DNext has to say for itself. And hopefully avoids the 4e powers trap. Where players have six monsters behind a bookshelf, and the first thing they'll do is look at their sheet and wonder what power to use, instead of maybe trying to push over the old bookshelf on top of the monsters.
I admit, as much fun as I have playing 4e, that's one aspect I miss the most. It started to leave in 3rd. Was fully killed in 3.5 (especially with the inherent idea of 'if it's not covered in the rules, you can't do it'. Maybe that wasn't the intent, but a LOT of players fell into that habit.)
