Mori Toshimichi, producer and director at Arc System Works and overseer of Blazblue series: "If I were to make a game based on something that wasn’t a complete original, which is what I have done in the past, it would be based on the intellectual property of RWBY. So each girl has their own kind of color, theme that they are associated with and the original creator has sadly passed away. If we were to ever make a fighting game of this, I would want to really spearhead that if possible."

Kerry and Miles (he retwitted it) seem to be pretty receptive, so who knows.
