I opened two hobby boxes for the new Rogue One Series 1 release. I did receive a base set from each box. Here is how the rest of each box looked:

Box 1
12 Death Star black base set parallel cards
8 Green Squadron base set parallel cards
4 Blue Squadron base set parallel cards
1 Gray Squadron base set parallel card numbered out of 100 (this looks a lot like the Death Star black parallel cards, the numbering on the back is what clued me in that it was a different parallel set)
8 Blueprints of Ships & Vehicles (full set of 8)
12 Character Icons (full set of 11 with 1 extra)
2 Character Sticker cards
4 Darth Vader Continuity cards
6 Gallery cards (this set does not have numbers on the card backs)
5 Heroes of the Rebel Alliance cards
6 Montages cards (also not numbered on the back)
5 Villains of the Galactic Empire
1 Star Wars Card Trader card with code for redemption on app
1 Paul Kasey as Two Tubes autograph card
1 Jyn Erso X-Wing bronze medallion

Box 2:
12 Death Star black base set parallel cards
8 Green Squadron base set parallel cards
4 Blue Squadron base set parallel cards
1 Gray Squadron base set parallel card numbered out of 100
1 Gold Squadron base set parallel card numbered out of 50
8 Blueprints of Ships & Vehicles (full set of 8)
12 Character Icons (full set of 11 with 1 extra)
2 Character Sticker cards
4 Darth Vader Continuity cards
6 Gallery cards
5 Heroes of the Rebel Alliance cards
6 Montages cards
5 Villains of the Galactic Empire
1 Star Wars Card Trader card with code for redemption on app
1 printing plate, yellow for card HR-10
1 Baze Malbus Y-Wing silver medallion numbered 23/99

I am glad that there is a base set in each box and that the base set isn't primarily character cards like the Force Awakens Series 1. None of the card backs have story or character descriptions.

I opened a box on Christmas even and pulled a Forest Whitaker autograph number 8/50 and then I Opened 3 more boxes two days after Christmas and I got 2 nice sketches and a Felicty Jones autograph redemption card . Each box had a medallion card and the correct number of insert cards.

Those are some great cards. Congrats!
