European retailer CoolShop has listed a release date of February 26, 2016 for the highly anticipated reboot. Nintendo has yet to confirm or deny this date. It is also highly likely CoolShop has merely made a ballpark guess on the release, and has no insider information on planned or expected release dates for any region.
For what it’s worth, it seems to be a reasonable guess. It is within the ballpark of a feasible release date, or at least release window. The tail end of February 2016 / start of March will see releases for games like Deus Ex Mankind Divided, Mirror’s Edge Catalyst, Tom Clancy’s The Division, and Hitman. These games also seemed like they would have been a shoo-in for a holiday 2015 release, but then had to get delayed to ensure polish and quality control.
