While we have avoided discussing leaks and rumors regarding the Switch on this site, this particular news piece has been confirmed as legitimate. A series of Hori Accessories for the Switch have been leaked. These range from Zelda: Breath of the Wild-themed skin sets and accessory packs to a fight stick and chargers as well as a base/stand for the system, chargers for the Joy-Cons and an ethernet adapter.
You can see some images below.
The fightstick has me very excited. I wonder what fighting games will be coming to the system.
