No way, this site has it at 1.4 million after 3 weeks in Europe so probably close to 1.8 million when the next 2 weeks are added.
That brings it to 8 million for USA+Japan+Europe and does not include Canada, Latin America, Australia, New Zealand, Middle East or the rest of Asia. None of those individually are big but should easily be another ~500k combined.
That brings it to ~8.5 million, then add 15-20% for digital and you have ~10 million.
I don't think Nintendos digital attach rate is that high. Probably 1m topds digital imo for NA, Japan, and EU. And 500-800k ROW incuding digital.
