Okay, folks, here's the thing...
*snips Ari's long, thoughtful post*
We'll have none of your reasonable logic here mister!!

I really don't understand the issue either. Clerics worshipped no gods and instead were focused on the elements, which we will have access to via the Elemental Chaos, which also has Primordials (aka elemental lords). Oh no, Dray might be Dragonborn! Who cares?
Dark Sun is being made for people who are playing 4th Edition. There are many of us with very fond memories of DS. When did the Cleansing Wars come about exactly? Was that part of the Revised box set or one of the other later books? I ask b/c I stopped picking up Dark Sun around teh time of the Revised box set b/c I thought the changes were terrible and the whole Cleansing Wars thing and Rajaat was pretty lame. So if they remove some of that, great. Retcon away.
The designers think they can make Dark Sun a fun and interesting place for peopel playing 4th Edition. I never expected everything to be teh sdame and I think it's silly if anyone ever did. We're talking 2 editions later people, D&D has changed a lot since the early 90s.
Oh yeah, Firefox, grey text, white background, annoying to read.
EDIT: Oh yeah, and I'm all for a logical thought process being used to examine things like geography and terrain and seeing how these things happen in the real world. Explaining the Sea of Silt was always interesting, b/c you would usually end up with one person that had some background that would have them disputing it which would lead to "look dude its magic", which gets really old. Dragons Bowl as old supervolcano? Awesome, that even makes some sense. Sounds good, make it so, roll on. Nothing major here.
