I was about to say the same thing. There are probably 10 outstanding massive 3.5 adventures, many of which are epic 1-20 level behemoths that could take a year to play through. A dedicated group of 3.5 players wouldn't really be suffering from lack of content.
More than likely, they'll even catch wind of some 4e changes they feel like adapting to their game.
Heh - I JUST had a long e-mail exchange with one of my players on this very topic. He broke down to peer pressure and bought his own set of rulebooks just a few months back. His comment to me at the time was "as soon as I do this, they're going to announce Fourth Edition". Sure enough - a few months later and boom, 4e gets announced.
I told him not to worry. I have exactly zero intention of converting my current campaign to 4e. It was designed with a pseudo Adventure Path framework in mind and I know exactly what adventures I'm plugging into the next six levels of play. And once those are done, the campaign was going to be retired anyway.
And after that I was planning to start Age of Worms. And I'm still going to do that. And it's STILL going to be 3.5 (because I don't want to do the conversions). And when THAT'S done I still want to run Savage Tide. And I'm getting at least the first Pathfinder Adventure Path - which will also be 3.5e.
Don't get me wrong - I'm very interested in where they're going with the new edition. I'm liking a lot of what I hear and given the design staff involved I think it's going to turn out to be a good game. But I have a ton of 3e stuff that I still haven't had time to use yet, and I don't have the time or energy to do conversions to a new edition. (It's painful enough to migrate adventures from 3e to 3.5e and the changes between those two "editions" were minor). And conversions are never as easy as updating stats on monsters and NPCs - I did a "conversion" of Castle Amber and even though the stat conversion was relatively easy, some things had to be completely rethought out because the tactics of the two games are so different - I ended up changing some bits of the castle encounters radically because a straight-up conversion would have been either insta-death or a cakewalk. I imagine that, given what we've heard so far, the switch from 3e to 4e is going to be similar in that regard.
I'll probably end up buying the new core books when they come out (I'm a sucker for novelty in its myriad forms), and some things may wend their way into my games. But my players probably have a good 2-3 years of 3.5e stuff to play through, and they're just happy that I run games at all

I'm far more likely to use this as an excuse to pick up used copies of 3.5e books that I didn't want to pay full price for when they make their way to the local Half Price Books.
