I don't disagree that cb, particularly online cb has made 3PP think twice. DCC 66 is the last DCC for 4e, future DCC's will be for Goodman's own game.
Several people have said they couldn't name two 3PP companies. There are over a hundred.
My only main complaint about 4e is the deep intergration with character builder. When I need software to build a character, complexity has tipped the scale.
My second complaint is the heavy focus on public play. I understand the need, etc, I just don't think it is as important to the hobby or the publisher as home play is. However, I don't think anyone in the business agrees with me.
To be balanced, I think the statblock is the best feature of 4e, followed by the move back to a single rule book (in digest format even).
I am not railing about 4e, or any other edition. I have some things I hope change with Next Iteration. There are some things from OD&D, Basic, 1e, 2e and 3e that I hope are in NI and about as many that I hope are not in NI.
Some of these 3PP products are really good, and I hope that NI encourages those people to contribute rather than feel frustrated.
