In the unknown chance that they remake Gen VII in the future, would you be pissed off if they remade SM rather than USUM with its improvements? From what we know, while they ARE third versions akin to Yellow or Platinum, they're upgraded remakes of the generation's primary pair in a way that differs from traditional third versions, and possibly meant to replace them in canon. Think what they did with fellow dual supplementary versions B2W2, minus the whole sequel thing and sequel story.
