This would probably lead to the next iTCG set to catch up with the program for Pirates. Because once you think about it. They haven't come out with anything for pirates iTCG wise, even no Pirate cards 
. Maybe they'll have their own Set 5/6/7/8 PIRATES.
And release items to make pirate stuff. Such as Pirate Taru weapons, Pirate versions of Winkels, Nevas, Glitter gloves, etc.
My guess on this though is,
They will have City booster packs.
Such as
Henesys- All Bowmen cards
Perion- All Warrior cards
Kerning City- All Thief cards
Ellinia- all Magician cards
Nautilus Port- All Pirate cards
