Always good to read people who are "in the know", even when the point in question is factually wrong. And (independently of that), as for Wyatt having a stronger hand in 4E than Heinsoo, that's just bolllocks. True, James "wrote" an entire book mostly singlehandedly - the DMG, bar the final chapter which Mearls and Baker co-wrote - in a remarkably short time of 9 weeks. In fact, it's such an uninspired rip-off of 3.5 DMG II and Dungeonscape that I've got a hard time understanding all those people who praise it like the second coming of our Lord, unprecedented in D&D. Obviously such people don't know their 3.5. Talking about uninformed opinions.As someone else in a position to know (on both of these points), I'll back Ari up on these.
In any case, I see Heinsoo and Mearls as co-writing the mechanics of 4E, and you'd have to be blind not to see their respective input in the PHB and MM. If you think the DMG or other things that have come out under the lead story designer will have as lasting an impact on the 4E product line as the core mechanics did (PHB+MM), I'm all ears - because I cannot even imagine that.
