Maybe they will release the unaltered trilogy. Every other interview regarding Ep 7 seems to mention practical effects being used- it is an idea they are spreading around to sell the film. It certainly seems Disney is aware of the overuse of CGI in the prequels and any negativity surrounding the "updates" to the original trilogy. It is a good thing to know this is in the brains of the people in charge of StarWars.

The director himself would certainly try to recreate the feel of the original movies as opposed to the Special Editions. A perfect lead in to the new trilogy would be a release of the unaltered original trilogy.

Gotta have hope I guess.
