It looks like GoBots is coming to DVD through Warner Archive's MOD program. I thought there were major rights issues with Hasbro, but it looks like that is not the case.
Warner Archive's Facebook:
Do you own the rights to Hanna-Barbera's Challenge of the GoBots cartoon series or its movie GoBots: Battle of the Rock Lords? I'd really like to see both on DVD some day.
