After going through the list myself on the App, I noticed the Stomp n Chomp Grimlock, and it is drawn to look like the TF4 SnC Grimlock... so expect that as a redeco toy this year.

Three characters have "Champion" avatars to unlock (Ironhide, Razorpaw, Prowl), which I think means that they are not going to be toys... as the characters that have toys, have a "Starter" avatar to unlock. (and they don't have a "Champion" avatar)

I'm surprised that there are several Megatronus toys coming, but none have been released yet or even announced... so maybe they are being held back until the character appears on the cartoon. (it must be on the cartoon to have that many toys)

That Pumpkin Optimus sounds like it could be a store exclusive for Halloween... which is just weird. More so if it was a regular release toy.
