Lol you guys expecting PS5 doing worse at launch than PS4 did in 2013....(PS4 sold 4'2M to consumers in just a month and a half and XBO did 3'0M in the same timeframe). PS5/XBSX are going to have an even bigger launch than PS4/XBO had, specially PS5, in my opinion. The hype for both consoles during 2020 is going to be very high through the year, and if PS5 launches at 400$ like PS4 did...., well, we'll see records sales again, probably surpassing 5M.
Switch: Is going to be again around 18-20M but if i have to be precise...., let's say something in the middle, so around..., 19M but i won't be surprised if it reach or surpass 20M again. Without competition during most of the year, Switch is going to dominate sales again this year.
PS4: Well..., if PS3 did 8'5M in 2013, I expect PS4 doing better, just because it's a more popular console and because 1st half of 2020 is nuts, so maybe around 10M sold.
XBO: This console is going to fall hard in 2020, and like I expected, is not going to reach 50 lifetime before its successor appears, so i expect around 2'5-3'0M units sold.
PS5: 5M, like i said earlier, i really think PS5 is going to start even better than PS4 and there's no reason to think otherwise. I think Sony is going to be prepared to make such gigantic launch worldwide. They're going to aim very high with this lauch, i presume, maybe with Japan launching simultanously this time.
XBO: Like PS5, hype for the console is going to be high too, specially in America and UK, and i expect doing better than XBO, even if it's more expensive, so around 3'5M this time, maybe even 4M if it wins in America against PS5.
2020 is going to be a fascinating and historical year, software and hardwarewise. It's going to be fun....
