Sorry to burst your bubble, but EA is probably going to make Crysis Remastered an Origin exclusive just like they did with Star Wars: Battlefront 2 and Mass Effect: Andromeda.
EA wants to promote Origin over Steam and GOG because Steam and GOG take a % of each sale to compensate them for using their platforms/launchers (and DRM, in the case of Steam).
It's just like how Activision-Blizzard decided to make Call of Duty: Black Ops Cold War exclusive to their company's launcher instead of selling it on Steam like they did with all of the other Call of Duty games.
The future of gaming is one where we will have like 10 different Steam-like launchers installed on our PCs because none of these companies want to pay the others to use their launchers.
tl;dr: unless you want to play Crysis: Remastered on Origin, I suggest you ignore news about the upcoming remaster and buy the original Crysis and its expansion (Crysis Warhead) right here on GOG while you still can. The graphics of the original are holding up pretty nicely despite the age of the game anyway.
