It had a record launch followed by serious shortages. They are sacrificing PS4 production and marketing and already sacrificed its Xmas 2020 to push its successor as fast as possible, moreover unofficial rumours say Sony is planning to produce 16-18M in 2021, anyhow for a first full year 18M would be really huge, actually the biggest first full calendar year ever for any console by quite a large margin, so I'd stay a little under that max unofficial prediction.
So, considering the little we can already know, I'd say 16-17.4M. Very optimistic, but considering Sony sacrificed the last possible big year of its current cash cow to make it happen, we can expect it to make all the efforts possible to achieve it.
