TFW2005 were lucky to get a 5-page preview of Reign of Starscream #4 from IDW Publishing, where we see things aren't looking too good for the Autobots still on Cybertron after Strascream's return with the extra information he found. RoS #4 will be out next week August 13th, while RoS #5 will wrap things up on August 27th.

Check them out here, and here at the IDW Transformers forum.
