Whatever they do, if they go for the variants, just preview them at the same time of the regular costume.
This is a case where multiple costumes as a variant is ok imho, more than any rainbow Hulk or whatelse. Hope they don't go full retard with a variant months after original PO, or even some kind of ultra limited 200ES black costume variant. This is not Storm or Diablo or Master Chief, people would be (rightfully) pissed to miss out on a different costume.
And by the way I say so having ZERO interest in Spider Man. Probably my least favourite character
