At launch the only thing that really matters is:
1. The price
2. The power of the console
Games do not matter that much at launch! Just look at the launch lineup of the PS4:
PS4 exclusive launch games from Sony back then:
Sony Computer Entertainment Titles:
Killzone Shadow Fall: 73% at Metacritic
Knack: 54% at Metacritic
at launch.
Later on, so not even at launch, we had more exclusive games like:
Driveclub 71% at Metacritic
The Order: 1886: 63% at Metacritic
So, it will take years until we see all those games you are talking about! I don't think we will see horizon 2 or god of war at launch! At least, Sony did not announce anything like that for the launch
And yes games are very important in the long run, but not at the start of the generation! And well, what did sony show though?
So far:
Godfall
Quantum Error
Do these games convince people to get a PS5 at launch? Will people buy a PS5 for these games? Can you compare those games to The Last of Us Part II? I doubt it.
I hope that Sony will announce more games for launch, there is still plenty of time, but well, the last console launch didn't really have acclaimed games.
Xbox on the contrary has Halo Infinite confirmed for console launch, this games has been in development since 2015, so, I think this will convince at least a few people to get a new xbox. And MS bought a lot of new studios, who are working on new games, and I hope MS will also unveil more games around June.
