I also am interested in a TITAN comic but IDW has been mum (with me, anyway) on the subject. Maybe M & M or CLB have better data.
Unfortunately, no news on my end. I've discussed a TITAN comic with all the various editors who have shepherded Star Trek at IDW. Nobody has outright said "No," nor have I entered into negotiations.
If IDW were to offer me a TITAN book, I'd happily take the job. With over 20 years of comic writing experience, and over a decade in Star Trek, I think I'd handle it pretty well.
