With the Nintendo Switch Direct happening later today regarding Splatoon 2 & Arms, it seems as though the release date has been leaked thank to Amazon. Arms will release on the Nintendo Switch on June 23rd according to Amazon US which is a usual Friday release for Nintendo. See the image below or visit the link here. However, Amazon Italy places it releasing on May 2nd, which is a Tuesday release which seems strange for Nintendo. You can see the image further below, or visit the link here. If we had to place our bets on a date, we would go with June 23rd.
