Keyword, could. But a few reports have led to this speculation. Wouldn't that be the ultimate gift this winter?  Granted there would be no action cuts or closeups of characters - probably just scenery and environments paired with the score of John Williams. I'd be willing to bet on it happening during this time. It isn't unusual for teaser trailers to release a full year or more before the film.

Posted today from Starwars7news.com:

A reliable source just said JW (John Williams) received a trailer from JJ Abrams on Monday, Oct 20. JW has already written new Star Wars music to accompany this trailer. This new trailer music will feature new music and will be recorded on November 15 in LA with full orchestra. Still determining if the score will be recorded in London due to advanced age of composer/conductor. 14 hour flight to LA not too kind on 82 year old.

And recently updated:

UPDATE: According to an UNCONFIRMED RUMOR (posted by record producer Ford A. Thaxton on FSM), the reason Williams will start working on Star Wars: Episode VII this month might be because Disney wants to release the first teaser for the film on Christmas Day. The teaser would feature original music written by Williams and recorded in Los Angeles.

And a third piece of speculation: A little research suggests that Disney has a big movie set to open on December 25th, 2014 — Into the Woods. The movie musical based on the Brother Grimm fairy tales stars Johnny Depp, Meryl Streep, and Anna Kendrick. It’s a big holiday release for Disney as they will surely want a good turnout for the big budget film on Christmas Day.

Don't forget Jurassic World, which is undoubtedly dropping a teaser or trailer soon.

And another Avengers 2 thing this Tuesday.

And like a million tons of Halo information.
