Acccording to the Nintendo Facebook Group, the image above appeared, which detailed that an upcoming Taiko no Tatsujin game is planned to be released on the Nintendo Switch. If this is true, then it will likely be showcased in Thursday's presentation. Special thanks to lokamp for the heads-up!
This was already confirmed as a fake yesterday :x
Really? If you can give me the source who debunked it I'd be very grateful, as I'll reflect that one on the Taiko no Tatsujin blog post I wrote earlier today.
