Robot Kingdom just posted pre orders for G1 Constructicon Collection Pack, available July 2018. They also list G1 Starscream (July 2018) and a G1 Legion 8 pack (August 1, 2018) that are also Walmart exclusives. The Legion 8 pack has pictures of Outback, Tailgate, Bumblebee, and Swerve. Looks like Hot Rod isn't the only one coming out in G1 packaging. This will be a site to behold if they're all on the shelf at the same time!
