Lifetime sales expectations for Triangle Strategy (Switch only)?

[Link_Nines.XBC]

This game seems to have good word of mouth, so I'll say it can reach 1.5M.

Not sure if it can reach 2M, the games in this genre that sell more then that tend to have social elements, like the ones in Fire Emblem 3H (or pairing characters like in Fire Emblem Awakening) aka no waifus no 2M+.
