Square-Enix is facing a shortage of Octopath Traveler in Japan, and they've already apologized for the lack of stock. The company also mentioned that a new wave of physical copies is coming in early August. While we thought that would help out quite a bit, it seems like it's going to barely be a band-aid.
Square-Enix has now said that the stock replenishment coming in August is "very little," which means copies are sure to disappear as quickly as they hit stores. Square-Enix has once again apologized for the issue, and suggested one more time that customers should turn to the Switch eShop to get the game.
