A'koss said:Iron Heroes had some very cool ideas on this front - particularly the easy-to-stat-up-&-run NPC & "Villian Classes". 4e should really take a page out that model.
Since Mike Mearls is one of the lead developers in 4e, and the author of Iron Heroes, I'm sure the idea has crossed a few minds. I think the monster "classes" will work something like this, actually.
