JesseVader, I think the "I gotta have it" aspect of the Sacul figure is the George-freakin'-Lucas likeness...there was no chance a figure like that would ever be released to the retail world, and a figure of Lucas was one of those fanboy dreams for quite a while at that point. At least I'd heard it fantasized about more than I've heard people calling for a "Talking Vader" figure.
I have to say (against the grain here, it seems) that I am extremely underwhelmed by a Darth Vader figure as this year's Celebration Exclusive.
You almost have to guarantee that the parts will be a kitbash of various Vaders at best, a straight rehash at worst.
While a voice chip is nice, boosting the price to $15 certainly cancels out any benefit there.
At C2, the first thing I did was hop in line for Sacul. This time around I'm not even sure I'll be going. A figure the likes of which I'd never see otherwise could've easily made that a no-brainer. Yet another Vader just doesn't do it for me...even one that talks to me about being at C3.
As a memento for the Celebration, Vader has some merit. But as a chance to fill in one of those "They'll never make that" figures, this is a letdown for me.
