I’m surprised that pocket didn't use the 20th anniversary as an excuse to relaunch the DS9 brand. I know the characters and locations have appeared in other books and will appear again this year as part of The Fall
but 2009 was the last time a book was released that said DS9 on the cover. With this years schedule announced that means 2014 is the earliest we can expect to see a DS9 branded book, a 5 year gap between books. The 20th anniversary could have helped pocket attract some reader interest.
