Actually Brant Bridges said this in the live chat: "C-3PO will make an appearance this month, but not in PF. We're still making progress on the development of the PF, and lots and lots of engineering and logistical elements left to solve for both Goldenrod and his domestic partner. Epan, this also answers your question"...
So didn't confirm the sneak pic of yesterday was 3PO neither said that it was a Legendary Scale Bust, 1:1 Bust or 12" figure... I assumed it could be the 1:1 bust as the 12" figure has been announced by Medicom not so much time ago so a 12" Sideshow version of 3PO should happen later... and I was kinda sure it was the lifesize bust as The next legendary scale bust to come is Obi-Wan... and others presented last year in the Legendary scale busts future programs at San Diego Comic Con... and 3PO wasn't in that list...
