But, it seems, Nintendo's listing of FGC-relevant publishers attached to the Switch wasn't for show. The HORI Nintendo Switch Fight Stick: it's real.
【情報初公開！】「リアルアーケードPro.V HAYABUSA for Nintendo Switch」の— HORI /ゲーム周辺機器のホリ (@HORI__OFFICIAL) March 3, 2017
From the looks of it, it is exactly identical to the Real Arcade Pro V Hayabusa lineup, just modified for Nintendo Switch compatibility. The signature angular look and red faceplate is otherwise exactly like the rest of HORI's offerings.
But there are lingering questions still: how does it connect to the Switch? Does it utilize the Joy-Cons' wireless connections in any way? And given that the Nintendo Switch -- the actual console itself -- is many times smaller than the standard RAP Pro. V stick, is it actually possible to store the Switch with the stick?
The Nintendo Switch currently has Ultra Street Fighter II as the sole game with which to use the upcoming HORI fight stick with -- a throwback to arcade fighter goodness, with a first person shooter mode attached. There are yet no confirmations as to what titles Arc System Works or other publishers will bring to the console.
