^No, Pocket MMPBs appear to fall under Gallery. The catalogue has a specific section marked Pocket Books/Pocket Star Books Mass Market Titles, and there are more than just tie-ins within that section.
I downloaded the catalogue and looked at every page in that section, and I do not see any other Trek titles. Typhon Pact is coming in the fall, or winter. I guess the summer is only tie-ins. Looks like I'll be re-reading Tolkien this summer.
