Who, Mattel? Jaks? Bandai? Nobody has the ability to produce quality 4" figures like Hasbro. And Big-H simply refuses to do so, and instead favors higher-margin, poorly designed movie crap.
Honestly, I'm to the point, having just last month opened a few thousand (no joke) figures from the 25th Joe, PoC, two joe movie lines, and pretty much every MU figure from the very beginning, I don't know that I care if they ever make good figures ever again. I can't make a dio big enough or make enough customs to use them as fodder. I'm swimming in a small mountain of joes and Marvel figures. Yes, First World Problems, I know, but it makes me pretty apathetic toward whatever lame direction all of the toy companies seem to be going. I've got my lifetime supply, and Hasbro can 5-poa themselves into oblivion for all I care.
Between Hasbro going full-retard on figure design and Marvel waging an internal war against the X-Men, there is zero chance the figures I want to see will ever get made. I'll use the figures I have and all the custom cast parts from lots of talented people to make what I want. Hasbro can go play in the traffic.
