Which pertains to the movies, not the comics, of course. For those who want both new stories and a few remakes of stories, that's what this comic is for it seems.
We honestly have no idea what the ratio will be. I can't imagine Where No Man Has Gone Before coming in at less than three issues (the movie adaptation was six) and still be satisfying. There aren't too many other episodes that I can see coming in under two issues. So if they "re-tell" 3 TOS episodes in the first year, it'll eat up at least seven issues and as many as nine.
