So far we know there's going to be a movie Masterpiece Bumblebee and an Optimus plus one other. If the series turns into an ongoing thing, who else would you like to see? The current ones listed are for the first movie's 10th anniversary, but there's no reason there can't be characters from the other films in future. I'd definitely like to have a Blackout, Starscream (though the Leader figure is exceptional already) and Barricade, plus an Ironhide and Ratchet. But I'd also love a decent Grimlock, maybe with an Optimus to ride him. As much as a great Knight Optimus would be, I'm not sure it can be pulled off at Masterpiece level, but they could reuse the engineering from the Bumblebee to make a decent high ocatane version (and it wouldn't surprise me if there were ROFT and DOTM Bumblebees done somewhere down the line if it continues past the initial three).
