Will Pokémon Legends Z-A sell better on Switch 1 or 2?

[Machina]

My gut feeling is that if another mainline Pokemon releases within a year: Switch. If another mainline Pokemon is 2+ years away: Switch 2.

Or, put another way, the Switch version is going to have a huge advantage Q1, but sales will drop like a rock straight after that. Switch 2 will have a significantly more modest launch because of the small install base, but it'll have a good attach rate and will keep selling consistently until the next Pokemon launches.
