Why will Gta 5 also appear for Ps5?

First of all I want to say that I have nothing against the game itself, but I find it strange that the Gta 5 has been out since Playstation 3 and is now being ported for the second time. The first time on Playstation 4 it is not bad since the game was very successful and many more people have a Ps4. My question is why would Gta 5 even be new on the PS5? Why is Gta5 coming and not Gta6, why is one focusing on Gta 5 and not on Gta 6?

Money.

The online mode is quite popular and brings a lot of money to Rockstar.

They want to use that to transfer it to the new generation.

It's easier for them to publish than a new part

The Ps4 is backward compatible. You can play any game from previous playstations on it, not just Gta V. So what exactly do you mean?

You want to milk out the last money from GTA 5. In addition, there were the most players in this game in 2019. In addition, Sony finds this very interesting because GTA 5 is free on the PS5 for the first 3 months, which is why some people get the PS5 because of it.

It is a cheap port, some people are sure to buy it. Rockstar brings GTA V to all possible devices. Wouldn't be surprised if they can get it on the switch too.

The Gta5 will come out with better graphics for the Playstation 5.
