Incorrect. And I don't know why you are coming at the argument from that direction; I never even implied it was a roleplaying thing or that 4e would be wanting in this way.
D&D to me has also been defined by common elements that have been part of the ruleset and (growing) metasetting since 1e and before. Dryads as beautiful forest spirits instead of treants with bewbs, evil chromatic and good metallic dragons, lawful good paladins, Gnomes, bards, the planes, all those things are definitive of D&D to me, and did not "come from me", and are being unceremoniously chucked aside for the first round of 4e books.
If I wanted a bevy on new races or whatnot, I could have got that from Arcana Evolved or Talislanta a long time ago. But they presented something I didn't want from my fantasy gaming experience.
