Have you seen
Art for Heroes & Villains, Vol. I -- Call for assistance!?
They are searching for already published comic art and give a nice list were they needed inspiration. So all characters listed are confirmed for volume 1 and they will use most likely some of the art posted in the thread.

Has anyone read the new Ampersand of this months dragon (in the free section, no DDI required)? All who said that essentials isn't a revised edition, what are you saying now? Just look at the 'weaponmaster'.
Also there is a new essentials update ( the pdf is called 'Nov2010Update')
Tieflings have become a Cha + Int or Con race

Still no Con & Int race with racial feats and they seem to want them more fitting the essential Hexblade than the 'old' infernal warlock.
