I dunno.
I showed these covers to a few friends, and I started running the Starter Set for them just a few weeks later. One of the players even wants to be the DM for the new adventure, and actually already bought the PHB, MM, and DMG for that purpose.
So, I'm not going to complain at all, especially since HotDQ was somewhat lackluster, to say the least (salvageable, though, if you didn't mind multiple prep days beforehand). Given that its written by people who have a passing familiarity with the guy that wrote the starter set, I'll give them a benefit of the doubt for the adventure. The only thing I'm worried about is the mechanical balance of the character options in the Adventurer's Handbook--splatbooks have a history of upsetting the balance of the core classes.
Those covers, even though they don't really scream "Elemental Evil" to me, are still quite awesome on many levels.
