More of the wave 2 amiibo, Luigi and Pit have gone on sale at Nintendo World alongside with Little Mac, Diddy Kong, Zelda and Luigi. Captain Falcon has not arrived there as of yet.
The Nintendo World Store is one of the first retailers that started selling 3 of the 6 Wave 2 amiibo today: Little Mac, Diddy Kong and Zelda.
This probably confirms there being a “split release” date for this amiibo set. We could be seeing Luigi, Captain Falcon and Pit later on this week.
