Glad to hear. Was getting a bit worried given nothing in the investor report, even with the reporting caveats. Hopefully it sells ~ 2 million (or more) lifetime. If we assumed this game cost something like $100 million to publish (say $12.5 million on average for each year of development) that probably is what they'd need to break even. Say Nintendo makes about $51 per copy, after all retail and merchandising expenses, and with price drops. 1.5 million copies sold would be about $76.5 million in revenue. 2 million would be about $102 million in revenue.
Also if we consider that Prime Remastered somewhat subsidized the development of Prime 4, it isn't as bad as it seems. If Nintendo made $32 per copy sold that would be about $43 million in revenue from Prime Remastered, which obviously didn't cost that much to make. A lot of the technical work on Prime Remastered is shared with/reused in Prime 4.
Hopefully 2 million copies is hit, and I think if that happens we'll get a Prime 5.
