4A Games has released a blog post detailing new things coming to the Metro series as it's the tenth anniversary since Metro 2033 has been released. As a result of the tenth year anniversary, you can visit the 'Metro Timeline' on the official website or on YouTube, which is posted here:
Other cool things include Metro Exodus coming to the Xbox Series X|S and PlayStation 5 next year. Improvements will include a faster frame rate, increased resolution, reduced loading times, and "stunning Ray Tracing features made possible by the new hardware." If players own Metro Exodus on the PlayStation 4 or Xbox One on digital or disc they will get the enhanced version on next-gen consoles for free. This applies even if you haven't picked up the game yet.
The next Metro game is in development and is coming to next-gen consoles and PC's. It comes with a complete overhaul of the engine and renderer to take "advantage of the new power, storage, and hardware supported ray tracing afforded by the new consoles." While 4A stresses that there will be a "great" single-player Metro experience, for the first time there will also be multiplayer mode added to the Metro series for the first time. Basically there will be both a single-player and multiplayer mode will be in the next Metro title, and that's all 4A has to share on that front right now.
There will also be a new IP launched from 4A sooner or later. The studio is hiring from both their Malta and Kyiv studios, and if you want to work with 4A you should definitely check it out here.
