I don't mean to beat someone when their down, but, objectively it was only a matter of time. They were plagued by a poor brand image and couldn't shake it. I'm sure that if you pull up any Queen discussion thread you'll find statements along the lines of "if you order a Queen, you better have it inspected before receiving it." Over the years I've seen their largest customers (dealers) running away steadily, especially when warranties are returned without even being addressed, you have consistent poor quality control, even poorer communication, high pricing, and a seeming unwillingness to innovate the brand...
...I'm not surprised.
