in 3.0 ver unity suport for poseDeformer and blendshape??
I wait for this
Unity 3.0 will be released this Summer. We don't have a concrete date. But you can upgrade now for a discount and early access ( note that early access is not yet available).
As for features, I do not know what you mean by blend shape, but it has been stated that there will be something for people awaiting soft body physics. All we can do is wait.
