I'd still recommend getting the diecast version of the mark 42 suit, I got mine (finally) last week & I absolutely love it..., I don't know if you've seen Kotobukiya's 1:6 scale statue/figure of the mark 42? But compared to the Hot Toys figure, the Kotobukiya version is pretty underwhelming to say the least (in my opinion).
Believe me I know it's an awesome piece. I probably watched every youtube review but I just prefer more red than gold on an Iron Man suit. Since this new suit is pretty much the same build as the 42, I trust HT will knock it out of the park.
