GTA V is hanging there few years now, so not anytime soon (maybe until GTA6 urives, lol).
Zelda BotW and MK8D are must have games for Switch, so I imagine they will stay in top 10 at leats untily years end. New Pokemon is coming soon so Sun/Moon will probably go down.
Crash/Splatoon 2 are still too young, but we could have Splatoon 2 hanging in there for quite time also because its selling around 50k per week in Japan alone. ARMS will drop in few weeks.
