If it is Bk3k, I'm in on an LE. No questions asked. Black Knight was awesome when it came out and took SO many of my quarters. And although Bk2K is quite dated, I still enjoy playing it once in a while.
Steve Ritchie has made so many stellar games over the years that I've played and loved. A few bombs as well of course.
For what it's worth, as his last title I'm sure that he'll pour his heart and soul into this one, whatever it is. But I do hope that is BK3K.
