Official Super Smash Bros. blog Ultimate in Japanese has recently been updated to include the official description of Mr. Game & Watch, one of the most interesting characters to be available on December 7, when the title switches to the Nintendo Switch. These details were shared yesterday, but they did not come to be offered in the western blog, which at this moment is still not talking about this character.
It's really weird because all the blogs in all languages they are usually coordinated. However, it seems that this character does not yet have its own blog post for the West. It is not known why this is and we will be awake if we offer more information.
