The new D&D Basic Rules are posted.
I expect I'll do a full read over the weekend and give you a lot more insight as I go. But, just after skimming the opening [which I'll re-read again], one thing stands out to me as kind of... awkward. Especially given the reason we moved AWAY from 3.5/3.0 to the 4E model was to fix the very problem.
Go read The Wonders of Magic section.
Though, the section on the Wonders of Magic makes me leery for our brave non-magical people. All of their examples are ways adventurers are screwed without their magical helpers. You need clerics or you will DIE. You need bards or you will be OVERWHELMED. Without wizards and druids everything is TEN TIMES WORSE. Even if everything is more balanced, someone may have wanted to say something about warriors and paladins being a protective shield in front of their more vulnerable members, just so it didn't seem like the warriors were just sort of there for other people to be awesome around.
