does anyone know if metro exodus will be coming to gog

If, then very very late.

Epic made a deal with DeepSilver to release the Game exclusively via the Epic-Launcher...

If they can't get people to come to their sorely-lacking Epic store through desperately-needed good, pro-consumer features, they'll railroad them with exclusives of every new game coming out, instead.

I'll wait.

At the earliest February 2020.
Not going to reward this company for this anti-consumer move.

Looks like Dying Light 2 will be the same since that is also owned by Deep Silver.
Buh bai Deep Silver and your games.

I really like having all games from a series on a single platform. I'm gonna wait until it comes to GOG (probably for cheap).

Of course, we will see exodus on GOG... but in few months at least !

I don't really get how a new store can a good thing for the consumer.
What I understand is that the developer gets a bigger part of the "cake" in the end.

Yes, and this is a good thing. But i would like to have the choice where i buy the game.
I´ll wait until it is available on GOG.
