I want to switch from Playstation 4 to xbox one, can I play with the same Gta and the same Fortnite account on the xbox?

So I want to switch from Playstation 4 to xbox one, can I play with the same Gta and the same Fortnite account on the xbox?

No.

No, but why are you changing now, wait until the end of the year, then new consoles are coming

No.

What does this have to do with the question?

No, unfortunately that will not work.

Because it is no longer worth switching to the xbox one

And why if I may ask?

At the end of the year the new consoles will come and you can save and wait for the money

Well then hold on tight and take the following information which will hopefully lead you to rethink and revise your statement.

Point 1. The questioner is concerned with current titles. He can play it for a long time on the current generation. In addition, the One S is now available in attractive bundles for little money. He can play both console and the games running on it for a long time.

Point 2. Not everyone wants and can buy a new console for the release. Quite understandable at expected prices around 4-500 euro.

Point 3. Microsoft has promised that all titles appearing in the first and probably second year will continue to run on the One after the series X is released. Thus, there's a technical advance in the new generation, but the games remain on the current generation, albeit with some limitations.

So you have enough information that on the one hand refute that it would not be worth buying a one now and on the other hand show you that it is up to the questioner that he already has a PS 4, the Xbox is now his own, including Xbox Only Title to name.
