PHBII and its assorted are for new classes, not old ones. And new races. They said that like, back when they announced there would be multiple PHBs.
I'm betting that the D race is Doppelganger. While Changelings and Shifters were first in Eberron, I'm thinking they're going to try and sell them as universal races, as they have a broader appeal than Eberron's high magitechness of the Warforged.
I believe in one of the designer blogs or perhaps a preview, the Shaman was mentioned in passing when discussing leaders, so dollars to donuts we'll see Shaman in the PHBII (along with Barb, Sorcerer and Druid).
The W class is intriguing. It might be the Wilder, but that sounds too close to the Sorcerer's schtick (Wild, untamed magic).
