That is a beautiful film. I can only urge you to see it. 
Maybe you'll be lucky and get more in September. 
Hey, how about a write-up on it, when you see it? 

Just checked on the DVDBeaver mailing list, and you are right. Somebody mentioned a season, but besides the two didn't announce any other titles. But "The Cloud-capped Star" will obviously be introduced by Ghatak's son. 
Enjoy.
