Too early to say, but Nintendo has a great chance:
- 2nd Switch holiday: there's a chance that, unlike previous year, Switch will have some kind of deal in November, which would boost it's performance in November. In December Nintendo is really strong.
- Sony has spread its games during all year. RDR2 is a very big title (and will probably be the biggest seller overall), but Nintendo could stack pretty big hitters (SSB, Pokémon?, Animal Crossing?) in Q3-4, which would offset RDR2 effect.
Of course it all depends on what games will be announced this E3.
