Jim Ryan, the CEO of Sony Interactive Entertainment, stated that more PS5 consoles will ship out in Asia and Japan from 2023. This is due to the resolution of a long-running issue in the supply chain shortage that has limited the production of the PS5. He thanks people for their understanding and cooperation, as well as apologizes for the trouble. [Thanks, ryokutya2089!]
When the PS5 came out in November 2020, the world was in the middle of a global pandemic. That on its own would be more than enough to disrupt supply chains. However, at the same time, there was a worldwide semiconductor shortage occurring at the same time. The pandemic exacerbated the issue. Semiconductors are vital in the creation of electronics, from cars to consoles, and without them, Sony simply could not make enough PS5s to keep up with consumer demand.
Ryan did not state what the solution is to the semiconductor shortage. He simply stated that Sony resolved the issue. It is unknown when exactly there will be more PS5s available on the market in 2023. Since Sony increased the price of the PS5 in certain countries due to the economic condition, it is unclear if the prices will return to normal as more supply is available. As well, Ryan did not note when the rest of the world can expect more consoles.
The PS5 is available for purchase, and will start shipping out more in Asia and Japan in 2023.
