Ps5 collection?

I have a question about the ps5 collection. There will be several games for free with the ps5. But now my question… The ps5 is quite expensive so I still have to save up, maybe I won't be able to buy it for another 5 months. Will the collection still exist? So does it stay available forever or is it just for people who pre-order?

They are then available forever, but I only think if you have PSPlus…

Are you sure? I would be very happy because 500 euro are already quite a lot, so I want to get something for it XD

Do you have PSPlus?

At the moment it will expire soon

Why? It is only available for ps5 right?

Okay, so it's like this: You can only download the game Bugsnax with PSPlus until January as a monthly game, all other titles in the collection are included in the subscription and stay as long as you have subscribed.

So is the PS collection also available for PS4? And by the way, thank you for taking so much time
