Harlan Ellison and his dispute over "The City on the Edge of Forever" episode of TOS is a story of Star Trek lore.  In fact, Harlan recently settled with CBS / Paramount over the issue of unpaid royalties for an undisclosed sum.  Now, the famous Scifi author has made it clear on his web bbs. (yup, we said bbs)

As reported by ComicBookMovie.com, Ellison wrote...

"Yes, I would likely try to steer him toward the original film idea I was asked to pitch, by the late Gene Roddenberry and a production exec whose name I have blissfully flensed from memory (but he had been, if I recall, a hairdresser or clothing designer or ex-boyfriend of someone or other, and he kept trying to press me to include the Mayan Calendar). ...
"If the very smart Abrams didn't want to go that way, I would be wide-open to rethinking such a film from the git-go." (source ComicBookMovie.com)

We'll see if J.J. takes Harlan up on the offer.
