Wooooww. Not a single one of those threads have aged well.
I mean...I think it's clear that a single gimmick or game or concept is NOT enough to float a console. No matter the console. The console needs to be balanced, it needs to show innovation but not go too gimmicky. It needs to offer people what they want while introducing new ideas and concepts. It needs to be familiar but still new and exciting. and it needs to have exclusives. That's why Switch and PS4 sold so damn well (probably the #2 and #3 top selling consoles of all time when it's all said and done, respectively). Both of them are New enough to be exciting with new ideas that make them stick out, while also focusing on the core gaming crowd that buy the most. Both have innovation but also have crowd pleasers. both have exclusives and their own unique take on how to play. (VR and portability). Both are accessible without being too bland.
PS4 showed that a good balance is super important. It was familiar enough to entice people, but everything about the console was done well. No one thing was stellar or groundbreaking, but they did almost everything right from day one. PS5 seems to be following in the Ps4's footsteps, but taking it a step farther with the new controller features, improved VR, and all the stuff with backwards compatibility that seems to be widespread across the industry now. Plus all the games. Just, so many games.
I think it was Scott the Woz that I heard this from, but look at the PS1 vs the N64. PS1 came into the market basically outta nowhere and completely dominated the market. It was the first home console of all time to pass 100 million units, but the console really didn't have much of an identity. N64, though only selling about 1/3 what PS1 sold, had a more defined identity. Everyone who had an N64 had Mario 64 and Ocarina of Time and Mario Kart and Goldeneye, etc. You talk to ten different PS1 owners and they could each have entirely unique libraries. the people who play Final Fantasy VII aren't necessarily the same people who play Metal Gear Solid or Gran Turismo or Crash Bandicoot/Spyro. The PS1 targetted a wide audience worldwide and hit just about every note correctly, so when the PS2 came out it became an absolute juggernaut while Gamecube failed.
PS4 and PS5 seem to be emulating everything PS1 and PS2 did. after a rough section with the PS3 - and Sony completely fucking up the first half of that console generation - the PS4 seemed to start fresh, by giving us a wide variety of different games in many genres, a mix of old franchises and new IPs and new takes on old IPs. The Ps4 had a bit of a slow start but ever since 2015/2016 it's been a steady stream of beloved games, both multiplatform and exclusive. The Ps5 is riding that wave, is backwards compatible, and has all sorts of new ideas and concepts that change how we play games. compare that to the only direct competition, which basically seems to be more of the same (it's just the same as last generation but with faster/stronger hardware, and few exclusives/new IPs), it's not hard not to see this as repeating history.
Based on the trajectories of the past 10 years or so, I see PS5 selling more than PS4 if only by a small margin, while its competition will hover around the same or even end up lower unless a drastic change happens. This has nothing to do with brand loyalty, it's pattern recognition.
Like I've said before, I don't even like half of Sony's exclusives, but that doesn't mean they don't sell or aren't well liked. I probably like The Last of Us less than anyone I know, but it still sold like 17 million units between its two releases (that's the first game on PS3 and the PS4 remaster, not including part 2) and got an astounding 95 metacritic. It's not for me, that doesn't mean it's not good.
Point is, if you look at history and current trajectories, it's easy to assume Ps5 will sell as much if not more than PS4, unless something drastic happens. Unless the competition REALLY steps up or they REALLY mess up, that's the path we're on.
