I was wandering around the DnD site on wizards and then things started to change. There is now D&D Insider option on the left Nav and there are pages for each of the sections. No real content yet but the intro pages are all there.
I think they are tying wildshape back into poly to simplify the rules. That way they are both treated with a single set of rules.
I certainly hope they do add 'water safety' to the survival skill.
