Attention dear North American based, Wii U owning Shantae fans. If you have been sat by your console waiting for the update to release, then be prepared to wait a few days longer.
While the update is in fact out for almost every region and every platform going, Matt Bozon, the creator of Shantae, has announced on Twitter that the Wii U version for North America will not be getting the update until Thursday. Nothing has been said as to why this is, but it is the reason we are given. So sorry guys, but you will have to wait a little bit longer.
