After the Japanese launch, Weekly PS4 sales remained well below 200K until the launch of Destiny (13 September 2014).

If Sony can maintain the same weekly trend (weekly sales above 200K) the PS5 will catch PS4 in a couple of weeks.

But at the end it all depends on Sony’s stock

Both Xbox Series and PS5 have had an absolutely atrocious launch window in terms of games, I can't ever remember a new generation starting in a more boring and barren way.

Apparently they've just decided that the hardcore fans will buy one even if there are no games, and according to that charts, they will indeed.

I really dont think so. Launch itselft is better for the ps5 as demon souls, miles morales, godfall and buggsnaxs all got much better reception than killzone, knack and resogun. and just looking at whats coming we see we have more big titles than just infamous.

On the xbox side I agree as I said in a previous post. 

PS5 is still very unimpressive in my opinion; Miles Morales is a crossgen expansion pack, Demon's Souls is a graphical overhaul of a 2009 PS3 game, and Bugsnax and Godfall don't look very good.

PS4 and Xbone had unimpressive launches as well, but at least they had games that looked properly next gen.

PS3, my friend. It was atrocious at best. I mean, they sold the thing initially on "Lair"!

Forgot about the Wii U already? 

Are you forgetting last gen? 

PS4/Xbox One/Wii U all had weak launch windows. Not only that but the Switch was literally carried by Wii U games. All I would say is that last gen was less "boring" because there was less cross gen but the only highly rated exclusive PS4 had was Infamous SS in its launch window. Demon Souls, Miles Morales, Astro's Playground, Sackboy >>> Knack, Shadowfall

Also we're in the middle of a pandemic. Games have been getting delayed left right and center. For PS5 Kena, Returnal and Deathloop were all intended to launch by end of this month. 

Interesting to see for me is how big the console market will grow in the coming years. Since the 7. generation new markets arouse/developed, especially Eastern Europe, Asia outside of Japan, Middle-East, Russia, Latin America and (South-) Africa. At the same time the global population has grown and will grow further which means potential more people to buy consoles in already strong established markets.

There's no doubt that the gaming market as a whole will have a steep growing market in the next years. However, how that translates into console sales has yet to be seen. For example, Japan is especially noteworthy, whereas traditional home consoles are in decline but the Nintendo Switch on the other hand is a beast over there.

Also, economy is an important factor, will we have a depression in the coming years or will there be a boom? Another question is how Streaming services will develop and how it will affect console sales or even wipe them out to become streaming machines.

Revisionist history and bad use of the word hardcore fan to describe people wanting to get a new console.  A launch window is what, six months?  By May 2021, there will new games such as Resident Evil 8, Returnal, fan favorites such as Mass Effect Trilogy, and others, if you extend it to 9 months, then you have Ratchet and Clank, FF7 and others as well.  The PS4 and Xbox didn't get anything on that level maybe outside TLOU: Remastered which came out July 2014 and Destiny from September that same year.

And Wii U didn't receive any post launch games until August 2013 (pikmin 3). 9 months without any major 1st party support
