The rumors of a Nintendo Switch port of The Witcher 3: Wild Hunt have been revived due to leaks and an international retailer updating their web store with pages for the game.
The rumors of The Witcher 3: Wild Hunt being ported to the Nintendo Switch first started last December when French retailer WTT.biz uploaded a page for the game which was swiftly removed. The leak was met with scrutiny from the fans, as it seemed unlikely that the Nintendo Switch could even run The Witcher 3: Wild Hunt at an acceptable speed.
It seems that there may be more to the rumors than anyone realized, as a user on Resetera named Jim_Cacher uploaded an image of a supposed leaker claiming that the Game of the Year edition of the game was coming to the Nintendo Switch. He also uploaded an image of Taobao.com showing the box art of The Witcher 3: Wild Hunt for the Nintendo Switch, as well as what appears to be a console bundle.
These leaks should be considered to be rumors for the time being, as there is still little chance that a port of The Witcher 3: Wild Hunt is even feasible on the Nintendo Switch. A non-Pro PlayStation 4 can have issues with running the game and the Nintendo Switch struggles to run games like L.A. Noire, which is far less taxing on the hardware than The Witcher 3: Wild Hunt would be. It's possible that the game could be part of a streaming service (like Resident Evil 7: Biohazard was in Japan), but the leaks so far have confirmed that the game will be receiving a physical release, which also raises questions concerning file size. The game is over fifty gigabytes in size and the maximum file size of a Nintendo Switch cartridge is currently 32gb, which means that the game has either been drastically cut down in size or it will require a partial download in order to work.
On the plus side, a port of The Witcher 3: Wild Hunt makes it feasible for Geralt to appear in Super Smash Bros. Ultimate as a DLC character. Geralt has already appeared in the Monster Hunter and Soul Calibur series, so it's possible that Final Destination is his next stop.
E3 2019 is only a few weeks away and Nintendo will be hosting a Direct on June 11, which would be the perfect time and place to announce a port of The Witcher 3: Wild Hunt for the Nintendo Switch.
