Looking at the DVD cover, it looks like the "Queen On Fire" and "The DVD Series" lettering could be the start of a series of DVDs (ie: something that would appear at the top of a library of DVDs to come). "Live At The Bowl" looks like it's just sort of a subtitle.
Have they mentioned anything about an actual series of DVDs being called "Queen On Fire - The DVD Series"?
