A very slight delay for physical copies.
Shantae's latest adventure will be arriving just before Christmas.
XSEED, publishers of the physical edition of the game, confirmed an earlier report from developer WayForward that the Wii U version would launch on December 20. The "Risky Boots Edition", which includes the game on a disc and a soundtrack CD, will launch on the 27th for Wii U.
Our Zach Miller provided impressions of the game based on the Kickstarter PC version on this week's edition of Nintendo News Report.
