Sorry, 36 weeks for PS5. Wii, at 33 weeks, hit 10 million three weeks faster than PS5.
Make of that what you will. According to Zhuge, Wii didn't have that many consoles manufactured yet. If someone has better sourcing, it would help!
I don't see the Wii mentioned anywhere in Zhuge's tweet though. And the link to the Sony announcement is worded very carefully to state that it is the fastest selling console in Sony history, without mentioning all time console history.
PLAYSTATION®5 SURPASSES 10 MILLION UNITS SOLD, REMAINS THE FASTEST SELLING CONSOLE
IN SONY INTERACTIVE ENTERTAINMENT HISTORY
Since launching in November 2020, PS5™ global sales have outpaced PlayStation®4, SIE’s previous record holder for fastest selling console
PS5 is the fastest-selling console in the company’s history and continues to outpace sales of its predecessor, PlayStation®4 (PS4™).
Wii launch 11/19/06 - 7/28/06 = 252 days to reach 10,169,429 units sold
PS5 launch 11/12/20 - 7/18/2021 = 249 days to reach 10,000,000+ units sold
Very important caveats to note:
I don't know what date the Wii crossed 10m units sold. But I do know that the Wii had a staggered launch (NA - 11/19/06, JP - 12/2/06, EU - 12/8/06), whereas the PS5 launched simultaneously Worldwide. So, the PS5 was drawing sales from Japan for about 2 weeks (13 days) longer than the Wii, and it was also drawing sales from EU (Sonyland) for almost 3 weeks (19 days) longer than the Wii. I think for these reasons, Sony themselves are making it clear that PS5 is the fastest selling PlayStation, without attempting to claim that it is the fastest selling console of all-time.
