Regarding the druids being the new super race, I doubt it.

They lack the stamina of the plate and mail classes unless in bear form. But I might be wrong. I also depends on the changes to the eclipse system etc.
Many classes gets boosts in one way or the other, and I actually think Blizzard is doing a good job at balancing the classes. But until the changes are in-game and people get geared up it probably difficult to see whats going to happen.
