I think it would be a good move if future games do refer to past characters that have something special and related to the viral experimentation, if not Sherry there are others such as Jill Valentine, Natalia Korda, Manuela Hidalgo and Jake.View attachment 1421
According to News Bot, who refers to Yasuhisa Kawamura, Sherry was planned as a superman from a new generation of protagonists who would fight face-to-face with Albert Wesker.
Maybe the developers could have taken this idea for Rosemary. I can easily believe that the influence of Umbrella will be impossible to exaggerate in the future, so its leader will be careless at one moment, but this moment will be enough to make him known. It will also be a good opportunity to remember about Jake.
Some do criticize RE 6 story due to Jake popping up into it without any kind of previous hint but since then I honestly feel like there's potential for Jake and I can't help but think of the developments should Chris and Jake cross paths again.
I'd imagine the story to continue with Jill and Chris team up to dismantle what's left of BSAA, and that the mission after this would involve Claire or Leon asking Sherry and Jake to help rescue Rosemary, since there is a chance that after the time lapse from village's epilogue someone from the connections might be interested in using all these strange altered individuals and perhaps create some sort of creature that display their strengths and abilities.
