Murph just said that they have been shooting a new D20 season

So in their NADDPOD podcast, they just released the finale of the campaign and in their talk back, they were discussing how crazy these last few months were (November-December) and he said that among all other stuff, they were shooting D20!

Given that Murph is not likely to be a part of the side quest, especially not when he is wrapping his 3-year campaign, it's safe to assume that they have just finished shooting a new Intrepid Heroes season!
