For Super Mario Odyssey, you can expect a bonus experience. This will challenge you to collect musical notes, coins, and instruments hidden in three stages based in Bonneton (Cap Kingdom), Bubblaine (Seaside Kingdom), and Mount Volbono (Luncheon Kingdom).
And then for The Legend of Zelda: Breath of the Wild, you can experience the whole game – aside from cutscenes – through the Toy-Con VR Goggles. This can be used with existing save data, and you simply need to change the display method to the Toy-Con VR Goggles in the Options.
The software updates will be made available on Friday 26th April, giving you some time to build the Nintendo Labo VR Kit before they arrive.
The Nintendo Labo VR Kit Starter Set + Blaster, complete Nintendo Labo VR Kit, and Expansion Sets will release at retail worldwide on April 12th.
