Moin master I wanted to get ps plus and nba 2k21 for 1 year but it would be stupid if I couldn't play it on the ps5 and no plus hater so I wanted to ask whether all of this would also be transferred to the ps5
Yes, everything will be carried over to the PS5. Sony announced it.
Playstation Network is still available as an online service, if you transfer your account you can also use it on the PS4 and therefore still have your PS + membership, so it was when you switched from PS3 to PS4.
Hope you are right otherwise 150 euro away
It is true. Was something similar from the PS3 to PS4 too. And Sony has confirmed it itself.
There's no "transfer" with PS Plus because it is not platform-bound at all.
It is still unclear for games. I wouldn't say for sure that PS4 games of which PS5 versions exist are also playable on PS5.
