The latest issue of Record Collector (Nov 2012) lists a new Roger Taylor album to be released in November in their "upcoming releases" section.

If this turns out to be true, it is possible it is the "Best of" collection that was mentioned a while ago. The collection may have a couple of new tracks such as "I'm a drummer in a Rock 'n Roll Band" and "Smile" that were previewed at a Queen Fan Club convention.
