I've not read any of the issue yet - but I picked up Sins #1 for 50p at London comic mart & seen at the back Nick starts of the text section with "Don't start your first series called Last Stand of ..."
So do we think Nick should do a first Wreckers series which is set in the past?
Why where the Wreckers not on Earth to take out Megatron seeing he is the main Con bad guy back when IDW started. They can't have been dealing with Thunderwing aftermath all the time. But if we have a series about Impactor on a mission. I'm sure Nick could place in story details that link into the 2 future series (already released)
This could also follow on from James' Impactor stories in MTMTE
