The PS3 never dethroned Xbox 360 in North America but did worldwide around January of 2013:

According to research firm IDC, Sony's PlayStation 3 closed its sixth year on shelves by pulling ahead of Microsoft's Xbox 360 in global sales. Where will the first two HD consoles rest if they retire at the end of 2013?

2013 was a wild year because the Xbox 360 ended up outselling the Wii in North America and it was around the time GTA V did release:
Nintendo maintains worldwide sales lead, though, thanks in large part to Japan.

But what I meant by my post was that the PS5 is expected to sell 18 million from April 1st, 2024 to March 31st, 2015. Next year it will most likely be down especially if GTA comes out after March 31st, 2026. So let's say the PS5 does 16.5 million next FY if GTA VI comes out next Holiday and 15.5 Million if GTA VI is delayed past next fiscal year.
Then I just don't see the PS5 receiving a huge bump from GTA VI the longer and longer we wait.
It is very rare but it is possible for a system to sell more than the previous year after the peak has been reached like I believe PS2 in FY2004 sold slightly more than it did in FY2003 and the 3DS sold slightly better in 2017 than it did in 2016.
But I just don't see the PS5 going from 16 to 15 million next FY to something like 18 to 19 million the following FY because of GTA VI.
I just am very curious to see how the market reacts to the PS5 in 2025 as Monster Hunter Wilds is coming and should give it a boost in Japan but I wonder what GTA VI does next year or in 2026.
