Sony filed their financials recently and included is the sale of 4.5 million PS5 units since it launched. Clearly more units were wanted as many were unable to find any in stock. By comparison the PS4 only sold 1.2 million units in the same time frame.
Sonly did mention that supplies for more consoles will be available in the market soon. It takes some time to assemble the machine parts in addition to the final assembly. Everyone was caught off guard by the demand for the console.
Supplies of PS5 and accessories should improve by the end of March.
