I'm calling it now, the Gree Mighty Mugg will cost $25 (due to the "Special SDCC Packaging") and the Executor Chamber will be $50. Meaning that SWS.com will sell them afterwards for, oh, double the cost.
I don't know, I'm not expecting much from the Chamber. Sounds like it'll be a rehash Vader on a small platform with the OTC Holo Emperor over a flashlight.
