If for no other reason than that it will inflate the price and all of the people who don’t care about the unaltered versions will still pay any amount for a brand new release of Star Wars day one, Disney will include the unaltered versions.

To DrDre’s point about how there’s a growing majority of SE/PT fans within the fandom, I would think many of those fans would still love to be able to see the unaltered OT in modern quality, to see the theatrical TPM and the IMAX cut of AotC. Even if they don’t actively want those things the way we do, I’m sure they would find it a nice bonus to have a historical archive of these films.
