So far each wave after the first has introduced to us something new- Wave 2 was Rogue, Wave 3 was Fleet Support, Wave 4 was Experimental, Wave 5 was Fleet Command.
Wave 6 has brought us the two-slot upgrade, but when I looked at the reveal a second time I noticed a trend in them. They each had titles obscured or face down, the hammerhead had what appeared to be 4 ship cards and an extra stack of upgrades. It got me thinking, 'What do these ships have in common with each other that no other ships so far do, and could make for an interesting rule for Armada.'
Then it hit me that obviously both of these ships were stolen by the Phoenix Rebels in the show.
This leads me to theorize that the third non-unique hammerhead title is one that will allow the Imperials to run them, and the face down Quasar Fire Title is the Quasar Fire that let's a single copy be fielded by a Rebel player. Maybe that stack of 5 face down upgrades in the Hammerhead reveal and 2 un-pictured upgrade cards in the Quasar Fire reveal will be a set of unique cross faction upgrades they are saving for later as a surprise. Maybe that is also why the Hammerhead is shown with 4 ship cards.
Anyway, that is my theory and my evidence. Is it likely? Am I crazy? Would it be exciting if both these ships were cross-faction, or is it a mistake to blend factions putting us in a scenario where we could end up with some weird mirror match of Hammerheads and Quasar Fires with one being supported by X-Wings and the other by Tie Fighters. Did you totally see this right away and I am the crazy one for stating the obvious?
