There is already a ton of content surrounding Dispatch for fans to enjoy: if you purchase the deluxe edition of the game, you get access to prequel comics establishing important characters. They are incredibly well-written and drawn, making the extra dough required to get the deluxe edition worth it in my opinion.
Furthermore, roleplaying group Critical Role, which also serves as producer for Dispatch, created a beefy one-shot (one-time roleplay episode) based on the game. It's set in the Burbank branch of the SDN, featuring a different cast of characters featured in the game, expanding on Dispatch's world in a very fun way. I highly recommend you check it out. I've linked it down below.
And that's all we know about a potential Dispatch season 2. As we get close to the ending of the game, I'll update the article with any rumors or potential confirmation of more Dispatch content in the near future.
