Hell yeah! Never read FMA, but Brotherhood was excellent, so I assume the manga was the same too. I didn't expect the mangaka to write a new one already, but I'm really excited about this and will be sure to read it.
It's going to be great to read a new series by the author of FMA. I've also wanted to read the Major (baseball) series at some point, so a boxing series by the same author is something to look into once it comes out.
