Over 100 million PlayStation 4 consoles have been sent to stores between launch in November 2013 and the end of June 2019, according to Sony, while Nintendo's figures indicate its hybrid Switch console is maintaining a similar momentum ahead of September's Switch Lite release.
Sony Interactive Entertainment has shipped more than 100 million PlayStation 4 consoles during its five years and seven months of availability.
Those figures are comparable with the PlayStation 2's achievements; Sony's popular year-2000 PlayStation 2, which is still the best-selling games console to date, reached 100 million units shipped by November 2005, after five years and eight months on the market.
The PlayStation 3 achieved 87.4m worldwide sales over the course of its 11-year 2006-to-2017 lifespan.
Given that raw PlayStation 4 shipments tended to convert into sales within two to three months, total PlayStation 4 sales are likely to exceed 100 million by September 2019.
SIE has not released PS4 sales figures since the start of 2019 and, like Xbox, is expected to launch a new console in the next year or two.
Meanwhile, the Nintendo Switch appears to be keeping pace with the PlayStation 4, having reached lifetime sales of 36.87 million in the two years and three months between launch in March 2017 and the end of June 2019.
For comparison, some 35.9 million PlayStation 4 consoles had been sold in the Sony machine's first two years and two months.
By that time, the PlayStation 4 had been through three holiday seasons' uptick in commercial activity, whereas the Switch, having launched earlier in the calendar year, is on just two.
Fans have been buying between 2m and 3m new Switches every quarter since launch, save for fourth-quarter sales which have shown a significantly boosted uptake.
In the final three months of 2017, over 7 million new Switches were bought, doubling overall sales figures; in the last three months of 2018, more than 9 million Switches were sold, increasing the overall Switch population by 50%.
These numbers come ahead of the September introduction of a Switch Lite console, designed to be used as a dedicated handheld, dropping TV Out functionality in exchange for longer battery life, lower weight, integrated controllers, and to be released with a price drop from US$299 down to US$199.
"Pokémon Sword" and "Pokémon Shield" then release in November.
