SONY plans to sell more 37 million PS5 units by the third fiscal year(March 2023).And somewhere in the fourth fiscal year(March 2024), it will overtake PS4 (60 million units).
From that calculation, They need at least 23 million units.
But since what you are asking is until December of this year, it won't completely match up.
