Just because many people changed their minds and decided 3E was better than 2E doensn't mean they won't also change their minds now that 4E is even better (if that turns out to be the case). This is not a contradition. It would just mean that the game continues to improve with each edition. And even if 4E turns out to be wonderful, that is not to say that in seven or ten years there won't be sufficient learning and maturing of the game to produce an even better 5E.
But to answer the OP, yes, I am already meeting resistance from friends about trying out 4E, even though the folks I've talked to about this have not for the most part kept up with anything about the content of 4E. One group of firiends has reacted with rejection because they don't want to spend money on new books and products. My brother, on the other hand, has reacted based concern that it "won't be D&D any more". Both are legitimate concerns. But I think both concerns will be overcome if the game is fun and a good DM offers to run a game.
