I think a lot of hype was garnered from Kit showing that in hand photo. After two years of luke warm anticipation from the promo shots and not much else to go on I think a lot of people are going, "hold up a minute, this is looking solid."
I know I'm one of them.
Also it was the top post on the Hot Toys subreddit, with the title specifically referencing that OSK had gotten his shipment in.
I'm really hoping I can grab one, I've had bits and pieces to put together a TOB Indy but it's sat for a long time now. Would love to finally build it out.
