And, BTW, I fully realize that a 2.0 is a massive undertaking. I don't have a clear idea how it can be accomplished. (All I really know are the steps that would kill the game completely, like invalidating current models.) Furthermore, the only other miniatures game I ever played -- which I also loved -- was Dungeons and Dragons Miniatures, which was itself killed by its own 2.0. So I'm really not advocating for 2.0 lightly, believe me.
(To be fair, though, DDM 2.0 was forced on the players to make DDM conform to the upcoming D&D4E. DDM 2.0 was not needed from a gameplay or organized play perspective. So it's not really an equivalent situation beyond the superficial similarities.)
