Just got an email confirmation that Tim Delaney as well as top sculptor Val Edwards (she did Obama for HoP) were indeed laid off. They didn't leave of their own free will.
Apparently, much like the recent moves with Rich Ross taking over for D-I-C-K Cook and George Kalogridis taking over for Ed Grier, The Weatherman is trying to rid Disney of anyone who dares think for themselves. All yes men (and women) all the time.
Still, trying to track down more info, but apparently Valerie let it be known she had concerns over quality control issues involving sculpting and AAs and was invited to go spend more time with her family.
Not sure on Tim Delaney yet.
