NIS has announced that The Witch and the Hundred Knight: Revival Edition, a PS4 remake of the original PS3 title, will arrive in North America on March 1. It'll be priced at $39.99, but NIS will also provide a special edition on its store for $10 more.
The game itself has been reworked significantly, with an updated visual style, the power to control Metallia, new content, and a challenge tower of sorts. If you enjoyed the original game it seems as if there's enough extras to warrant another playthrough.
Personally, I found it lacking, though I liked the art style on paper.
