Also, the series will continue at some point (hopefully).

Shantae, the hard-to-find Game Boy Color classic, is coming to 3DS Virtual Console eventually, according to WayForward's Matt Bozon.
Currently, WayForward is waiting to hear back from the ESRB, and after that, it will be up to Nintendo to decide when exactly the game will come out.
The game was published by Capcom originally, and as such, the Capcom logos will be removed for the Virtual Console release. WayForward holds rights to the game.
Shantae received a DSiWare sequel, subtitled Risky's Revenge, in 2010. Another game in the series is always on the mind of WayForward, specifically series mastermind Matt Bozon, but they are currently determining when and where the series will continue.
