As with many of us, the real world got in the way of our projects/hobbies. If I recall correctly, Dax had some computer issues and lost a lot of his coding work. Very few people play BW2 anymore, so demand wasn't there either. And then there were issues with hardcoded parts of the game that were a pain to deal with. Basically a lot of stuff all came together at the worst time and the project fell through.
