I haven't been keeping up with the thread, but just wanted to chime in on my experience with the "schism" at WWD&DGD on Saturday.
I was there all day and spoke to about ten people that had come in to see what was going on. They were a mix of 3e and 4e players, but interestingly all the 3e players said that their opinion of 4e had improved after playing it. More than one used the word "enthused"

.
My point is simply this - it's really hard to know who does/doesn't like 4e until they've actually played it, and a good game (in whatever edition) is always more fun than a bad one, no matter what system you're using. Happily, I was in a good game.
Looks like in Brighton, UK, the schism isn't really an issue.
