My conversion to 3.X started with some of the first trickles of info I saw in Dragon magazine. To this day, I don't regret it. There were only a few things I thought earlier editions handled better than 3.X.
At the time, my main group was a triad of gamers who had been gaming together since the mid-1980s. One of the others started converting his PCs as soon as he had access to the books.
The third only converted after about a year, so despite my answer ("immediate changeover"), we didn't actually start using 3.X as a group until at least a year had passed.
We may not be the majority, but there are significant numbers of us...at least anecdotally.

Come on, there may be a few people wrapping up campaigns before they switch, but the constant theme is that there are lots of people who have absolutely no intention of EVER changing to 4e. They may drop 3E for a hundred other things, including dropping out of gaming altogether, but 4e isn't on the list.
