Gamble old games on the new PS5?

A short question. Most likely, the PS5 will be released in the next 1-2 years.

Now the question arises: Can I play my games, which I bought directly from the PS Store, on the PS5?

Would be a pity if I had to buy the same game again. Does this also apply to the CD games?

Of course nobody can know that, but what do you suppose?
And what about the competition XBox?
How do they do that?

You can't play PS3 spells on the PS4. Why should that be different again at 5? The probability is high that it does not work.

You should first keep that in mind, what comes with the five or not everything.

Uh wait a moment, I'll just call my insider contact at Sony, who can give me this confidential information for sure immediately.

But seriously, where can someone tell you? PS3 1st Gen went, later PS3s and PS4 not again, XB1 can. Pattern: Unpredictable.
