Through the first nine weeks available worldwide the PlayStation 5 is ahead of the Switch and Xbox Series X|S by a fair margin. The PS5 is ahead of the Switch by 1.74 million units and is 2.09 million units ahead of the Xbox Series X|S.
The PS5 has sold 4.82 million in nine weeks worldwide, while the Switch sold 3.08 million units and the Xbox Series X|S 2.73 million units.
Looking at the marketshare through nine weeks, the PlayStation 5 currently leads. The PS5 has a 45.4 percent marketshare, the Switch sits at 28.9 percent, and the Xbox Series X|S at 25.7 percent.
I love how people quote sales numbers like fact when they actually haven't been announced (and won't for any hardware MS Sells). MS and Sony are both selling everything they make, which is great for both. I fail to see why Switch is even compared, it's a budget handheld system at neither MS OR Sony view it as competition.
Why do gamers even care about sales figures? Unless you are a shareholder in Sony/Microsoft/Nintendo, it doesn’t really make any difference to you.
So let's put out numbers starting nine weeks ago and make it sound like the Switch has to somehow catch up to the PS5. Considering the Switch is some 70 million units plus ahead. Genius
