I personally think Disney will focus entirely on new content for the next 8 years. New films in 2015, 2017, and 2019. Each will have its own home video release.
Then, in 2020 (assuming the distribution rights for the originals goes to Disney as I've read) they'll pull the others out of "the vault" amd release a 9 film box set with (hopefully) the unaltered restored OT as an added hook.
