During the recent Nintendo Direct, Bethesda announced the DOOM Nintendo Switch version and it will be released by the end of this year, without giving any particular release date.
However, the Czech retailer called Kuma has updated the DOOM (switch) game page on his website and has included a dedicated FPS card, marking as the release date on December 13, very close to the Christmas holidays and in perfect alignment with what Bethesda announced. However, developers have not released any information about it, so we advise to take it as a pinch of salt and wait for an official press release.
In addition to DOOM, Bethesda also plans to release the much-beloved The Elder Scrolls V: Skyrim on Switch, an adventure that will span from November 17, 2017, and Wolfenstein II: The New Colossus, which will be released next spring. You can find all the relevant information here.
