The instruction manual of LEGO Star Wars Mos Eisley Cantina (75052) is the first acknowledgment of LEGO Star Wars 75058. You can see which minifigures will be included. It’s a retailer exclusive so we won’t have images of the set until the retailer is ready to show them.
Set 75058 will include Obi-Wan Kenobi, Qui-Gon Jinn, a Naboo Security Guard, several battle droids and a maintenance droid. This will likely be a Naboo themed set and rumored to feature either a Trade Federation AAT or MTT vehicle.
