I tried posting this earlier in the conversation but it was eaten (it encountered an internet sphere of annihilation

). I hope this isn't too far behind the conversation, although I have read the rest of the thread (and now I'm TIRED!

).
I just turned 40 this year also, and I am not switching to 4E, but I really don't know if it has anything to do with my age or "generation". I'd be interested in seeing a poll of those who switched and didn't switch based on age group. Maybe there is a generational facet to it, maybe there isn't. Hmmmm.
Anyways, I agree with Jeff for the most part. In fact I probably feel about 90% the same way. So I'm not trying to belittle him or his opinion. But...
I don't think that WoTC decided that I'm not their target customer anymore, I think it's that I decided I'm not their target customer anymore.
Now, that doesn't mean I have anything against WoTC. I don't. I think WoTC made a smart business decision based on their financial and market research, and on customer and fan feedback. They just used that information to go in a different way than I would have preferred. They made a game that's popular, achieved the goals they set out to achieve, and I'm sure it's making money hand over fist, and I'm happy for them.
I'm just a little sad and disapointed (in the situation, not in WoTC) that our paths are diverging. But the reality is, it hasn't changed my game or the enjoyment I and my players have when playing it, one single bit. When the game is afoot, and the dice and monsters are being thrown about, the whole 4E/3E thing is the farthest from my mind. And I think that's all that really matters.
Now, maybe in 5 or 10 years, when 5E comes out, it may feel more like the type of game I prefer. I may even feel that D&D has gone
"back to it's roots", or that I want to
"play more"
, but that's for the future. I do think it's less from anything WoTC has done, than it is my tastes have diverged from theirs.
