Now, we have seen several Sonic Boom trailers here in this wiki, and all are in English. The big question is, Will there be a japanese version as well?
The answer is yes, but with a little tweak to it.
It will be called Sonic Toon in Japan. The same characters and designs will be there, but it is unknown if the show will be released in the same month as the US version. And it sort of rhymes.
That's all!
