You do realize that worlds don't need trial decks right? They're only good for getting people started, but they do usually contain 1-2 good exclusives.

Also it's likely because Tetsuya won't be as main as a character as we expected him to be.

Katana is getting a trial deck probably due to Zanya becoming one of Gao's main rivals or something like that, and Dungeon is getting a new one for an unknown reason at the moment, but I'm pretty sure it's because Gao is going to switch to Dungeon World. However it is odd that it's going to be released after set 3 instead of before.
