Even though the outfits are notably different between the games in certain aspects, the overall style is close enough that I think either works as being visually John Marston. As such, if RDR2 is chosen as the base look, then I'd personally still be satisfied with the proposed separate rdr1 head sculpt to cover all bases. I would say that the bandoleer and the shoulder slung rifle holster and rifle should be part of the overall package somewhere too, though, either with the core release, or with the second head sculpt, so folks can still give him his rdr1 styled look.
