Saw your tweet, and wow. Just wow what a great figure set.
To my Tweet point, Hasbro's competing as the "budget" line at this scale, and I get it, but what you get is so vastly superior with Mafex and such... even the Bandai kits generally speaking.
IMO if you wanted to get into 6" as a small side collection, you'd be so far ahead buying out of Japan than buying Hasbro at this point... Mafex is doing human sculpts and things, Revoltech same... Bandai's all masked guys so far with the kits, but you never know (though I wouldn't count on anything else unless they give pre-painted heads in kits, which I doubt).
Hasbro has the branch-out space, but I think I'd prefer the higher-end stuff as a side collection to my 3.75" figures. Hasbro REALLY is left in the dust... yeah, you pay more, but you get what you pay for too.
