I never have and never will buy import figures, so I don't need Mattel to try to compete with those. I'd personally rather have relatively affordable world-building with hundreds of figures than a few dozen exquisite figures of only the most well known characters. There's just not enough of a difference to me to justify a price point 4x that of the readily available domestic stuff.
Mattel will win a lot of fights by virtue of being the only game in town. I'm eager to replace my DC Icons Swamp Thing and Harley Quinn, Mattel Wonder Woman, and MAFEX Catwoman and Joker. I don't even own a classic 6" Deathstroke. If they make those figures and they're decent—like Marvel Legends decent—I'll buy them.
I doubt Mattel will top my MAFEX Nightwing or Bane—they're among the best figures I own—but I would replace others, like Mezco's Constantine, if Mattel's figures were good enough. I don't necessarily need Mattel to compete with imports, but doing so would open them up to a new audience (like me).
By the way, if their DC figures are as good as the movie MOTU stuff, I'd argue that they
are competing with imports. I could absolutely see a MOTU movie-quality Mattel Batman dethroning my MAFEX Batman.
I can think of hundreds of DC characters that might sell at $12.00 that may very well peg warm at $29.00.
I don't think so. As Damien pointed out, Marvel Legends is the model. Your 35th Spider-Man purchase pays for characters like Hypno-Hustler. Hypno-Hustler won't move as many units as Spider-Man Variant 274, but that's baked into the business model. You cook up a few great sculpts like Hasbro's Vulcan body, re-use them regularly, and use that to pay for unique base bodies like Constantine. Marvel Legends has been doing that for more than a decade now. Mattel should be able to follow the same pattern.
As far as price goes, I expect these to be around $30 by the time the line begins. That's the going rate for collector-style figures, even relatively cheap domestic brands.
I won't buy the extremely niche D-list DC characters, but if I were interested in them, I'd want them fully articulated. PanchaMaestro said as much, and I expect most of the board agrees with him.
