In regard to a patch, Chris told me, "We're working on one, but we don't have an exact release date yet." Feargus was more specific, telling me: "We wanted to release something fairly quickly based upon some feedback we were getting. I think [SEGA] wanted to take a different approach by gathering more information over a longer period of time and provide a patch then. That's what we're figuring out right now."
Unfortunately, the possibility of DLC doesn't seem as good. Feargus tells me, "I don't know if [SEGA is] talking about that at all yet. I can say that we're not working on any DLC right now. We'd love to, but we're not."
