I disagree. If hot toys wanted to move into other formats like 1:1 busts I bet they would take a massive dump on sideshows. Thier artists are so much more talented IMO. And they tend to be more accurate and they actually take on board ideas from buyers. Unlike sideshow who tend to go against what people want.
As MF stated, most of their 1/4 pieces arent nearly as good as their 1/6 scale figures. I dont care how good HT artists are, theres a huge difference between 1:6 and 1:1.
