It's the end of August and there's no announcements yet regarding 2018. I think we have to consider it a very real possibility there will be a gap of at least the first 2-3 months next year.With any luck there wont be a gap in releasing novels early next year.
Everyone else does print editions of their e-book originals, so there is financial viability to it. So it likely is just a case of those calling the shots of the Trek line not being interested in doing so. Although with potential gaps in the publishing schedule, this idea should be considered, IMO.I think after so many years of them never rereleasing ebooks as paperbacks we have to acknowledge that either the current editors just aren't interested in ever doing that, or it's not financially worth the effort in today's marketplace.
