Phil Spencer, Director of Xbox division at Microsoft, said in an interview with the former head of Nintendo's IS branch, Reggie Fils-Aime, that there are certainly enough new consoles for everyone. The coronavirus pandemic did not disrupt the supply chain of Xbox Series X manufacturing processes. On the day of launch, the quantities in the shops are to be sufficient to meet every demand.
As Phil says:
“In our supply chain, we feel good about the hardware side. Feels like we'll be able to get enough units. And you know, we're pretty committed, as we've talked about to a worldwide launch, which regretfully, we didn't do with Xbox One. You remember watching that from Nintendo campus. It took us months and months to hit some of the incredibly important markets and worldwide launch is important to us."
The Xbox Series X will be released at the end of the year. A full record of Phil Spencer's interview:
