It's unclear when The Legend of Zelda: Breath of the Wild is actually going to be released, but according to Eurogamer we may have some more information.
According to their claims, sources have said that Nintendo wanted the Switch to have a very strong launch lineup, hence the decision to make Breath of the Wild a launch title in Japan and North America, however, there's no word on Europe's release date, according to the same rumour.
In the same rumour there are claims the Nintendo had always wanted the game to launch in March in Japan, whereas other claims suggest the decision to stick with March was only made at the end of last year. Would you want it as a launch title?
