There are plenty of posts about this in other comci threads, so I'll be brief:
Sales were not what IDW had wanted, they were constantly dropping, I think they were down to the 15,000 or so.
So All Hail Megatron was pitched and accepted to take the place on the "-tion" series as the #1 Transformers book by IDW.
Looking For: Wreckers Saga TPB Collection (with Requiem)
Cool, thanks.
I always have a hard time finding these comics as the shops that sell them are not exactly close nor on the way from where I live or work. I guess that I will need to wait till the next Parra Fair to get Spotlight: Sideswipe.
