Is Benedict Cumberbatch's "john Harrison" Coming Back For Star Trek 3?

The actor dodged a question during a Graham Norton interview. Read the full article on AICN Benedict Cumberbatch was on The Graham Norton Show today, and answered one of Norton's "contractually obligated questions" in such a manner that it prompts some curiosity.   When asked "Are you in the next STAR TREK?", he quickly gave Graham a snip, "No comment." When the audience cooed at the tease, Cumberbatch leaned into it and fidgeted knowingly in his chair.   I'm betting that, at the very least, Cumberbatch knows for certain whether or not his STAR TREK INTO DARKNESS character will return in Roberto Orci's threequel.
