It's possible, but I doubt it. If it has an impact, it will be positive I can tell you that much.
The same people who bought a 3DS system back in 2013 or 2014 for X/Y or OR/AS will most likely get Sun/Moon. And it is possible that the people who are some back into Pokémon again as a result of Go may splurge and buy a 3DS system for Sun/Moon and the other Pokémon games. And it's not that expensive anymore since the 2DS is at $80 now.
