All the way back in 2015, two games were announced for Nintendo NX — the first to be revealed for the in-development console. They were Dragon Quest 10 and Dragon Quest 11, the latter of which had yet to be released on any platform.

Now it’s 2018, and the Nintendo Switch, as the NX became, is a massive hit. It would make sense for Square Enix to ensure that Western fans get their choice between PlayStation 4, Switch and Windows PC versions of Dragon Quest 11 once it launches this fall. But the Switch version of the game remains under construction, without any hint of when it will be ready.
