I'm among the crowd that wouldn't really want the set without new legs... Upper body on the figure is great, but from the waist down Scorch was a weak action figure. No knee joints on figures, especially at these prices, is pretty obnoxious these days... A 4-pack of the "team" is bound to be overpriced as it is, so utlizing the current sculpt + new legs wouldn't really hurt things...
Of course I don't look at lacking articulation as irrelevant... It's probably the most important aspect of action figures to me. Other lines have blown past Hasbro's standards, so it'd be great to see them set the bar a little higher... especially on army builders like these.
