Let's see if we can make a list of things to do for AS:
- Gate of Memories DLC.
Physical rewards from both Kickstarter Campaign.
Relaunch the English RPG line.
New book in Spanish.
Gate of Memories Switch Port, maybe.
Mind you, I have made this list according to what they have said on both Kickstarter and Twitter (Switch port was mentioned by them on Twitter). If this list is correct, then I don't think finding a English Publisher should be a priority, at least until the issue with the physical rewards has been adressed. After all, according to the last update they were releasing them in December 2017/January 2018. Now, we are on March, and there is no word about it.
What I'm trying to say is: Don't expect anything from the RPG line until Gate of Memories has been completely finished, since unlike the Kickstarter campaign, they have made no promises about the books.
