I have to go against the flow: Yes.
Compared to any point in the past people are more for the new edition than they were; this trend is going to continue.
…every time someone starts a thread about “too many base classes” or “too many options” it’s a sign the collective consciousness is shifting.
Personally I think we’re still further off than most people (or at least a those who feel like it’s a gun pointed at their head), the
economics reward Wizards taking their time and I don’t think Hasbro is going to cut off the cash flow for a while yet; they still haven’t produced a lot of books that people want to buy (collection of feats, updated Epic stuff, more Eberron, etc).
Having said that it is possible that the designers have lots of new ideas for improving parts of the rules and want to write a new version (I mean… if you worked at Wizards wouldn’t you want to write a new version of DnD and get to be the next Monte Cook?); certainly the appearance of critical (and in some cases virtually nonsensical*) articles about the current ruleset on the wizard’s site suggest a trend in that direction.
*=I think the 4 part polymorph article actually made me stupider.
But, yes, the community is much more –for- the 4th edition than they were before.
