Thanks to the master DCPI list being kept up-to-date on 
Yakface.com, a DCPI tracking website and some super-sluething by a coupleof LEGO 
Star Warsfanatics it has been determined that the 75219 Gorgon (code named 
Solo set), which we first reported in our 
Summer '18 set reveal is the same as the Hot Wheels Quad Hauler Battle Roller.

However we haven't been able to determine if this is the Conveyex train or the Imperial Hauler, but with help from 
Eurobricks.com we've been able to build up an idea of what this set - or potentially 75219 Gorgon (code named 
Solo set) - is.

The information received has been collected from the Walmart stocking system which - while this isn't conclusive - it leads  Rebelscum to believe we're getting close to the truth.
