Welcome to the forum fryan!
The XB 40 was discontinued after about 10 years because it was expensive to manufacture and failed to sell enough to warrant keeping it in the catalogue. Had the decision been mine to make, I would have kept it in the program, it’s a unique instrument. Before it was introduced, I warned that players would probably need about 10 years to really figure out how to deal with it, and events have shown that was a realistic assessment. I’m glad that people are enjoying playing them!
