Well, seems like the TFA Blu-ray/DVD will be released April 5, 2016.
Abrams have also said that a good portion of the deleted scenes will be made available.
I hope that bit from the novelization where Leia sends an envoy to the senate on Hosnian Prime is in there. I think that one scene would clear up a lot of the vagueness about the state of the galaxy that a lot of folks have problems with.
