Episode 150 of the Seibertron.com Twincast Podcast sees the return of Mainframes, which takes a deep look into the world of Transformers comic releases from IDW Publishing. This episode's focus is on the entire Sins of the Wreckers series. This episode will completely "spoil" this issue, and many plot points in the greater IDW Transformers story arc, for readers that have not caught up to this point in the story. Speculation abounds along the way, with several stops to look at where the series has been and where it might be going. Analysis of the structure, tone, and character work in the book is also in the scope of discussion for the team. Listener questions from the Seibertron.com forums are also fielded, with some answers being definitive, and others being a nice surprise.
