I fail to see how the release of 4e is going to get people interested in looking at 1e. Seriously; what's the logic there? Sounds more like wishful thinking to me. I think 3.5e players like 4e, they'll move to 4e. If they don't, they'll stay with 3.5e for the time being. Why would they suddenly look to 1e, OSRIC or C&C if they haven't already?
I never understood why people think there is such hostility. Most 3e players (at least those that post and vote in polls and stuff around here, and those I know from my local groups as well) all played the older editions back when they were current. I know I did, and I left D&D altogether because of 1e, honestly. It was a clunky system, not a simple system, and it didn't allow me to do what I wanted with the game without massive rework. I'm not saying 3.5 is the be-all end-all either, but it benefits from decades of watching D&D, the rest of the RPG market outside D&D, and seeing what works and what doesn't and putting it all together in a reasonably attractive package. I wouldn't go back to 1e; and frankly if my group were suddenly consumed with a desire to do so, I'd probably give the game a pass.
But I'm not hostile towards it. I do get a little peeved at the elitist grognards who think it's cool to constantly piss on 3e, though. Not that I'm sensing you're one of those, but sadly it's a common vibe from some. I am somewhat hostile towards being insulted for my preferences.
