I LOVED the manga, it felt way more like a classic RE game then the last few main title releases have and the characters were likeable and developed. I would be overjoyed if it was ever developed into a full length game at some point or another but sadly that will never be the case. Regardless, it's an awesome read and I highly suggest anyone who has not read it give it a shot. You may end up loving it like several of us have.
The first volume will be released in America in November 2014.
Maybe Capcom will plan something to go with it. Otherwise, it's odd that they would go to the trouble of translating and releasing a prequel manga to a game from 2012. Well, it doesn't seem profitable anyway and you know that's Capcom's main goal.
