The official Super Smash Bros. blog. Ultimate in Japanese has been updated recently to include official descriptions Mr. Game & Watch, one of the interesting characters that will be available next December 7 when the first title on the Nintendo Switch. This detail was shared yesterday, but it never came to be offered on a western blog, which is currently still not talking about this character.
This is really strange, because all blogs are in all languages they are usually coordinated. However, it seems that this character does not have his own blog post for the West. It is not known why this is and we will be vigilant if we offer more information.
You can see Japanese entries on this link and trailers of Japanese characters below:
