The recent experimenting with extra heads packed in is encouraging, and I wish they'd do it more (I would have loved for the Retro G1 Bumblebee to have come with both the Bumblebee head and the Goldbug head for your choice of cartoon or toy accuracy). I am 100% behind the idea of standardized head connections wherever possible.
I was going to say something about Titans Return, but ehh.
I've been hoping for additional/alternate heads for Transformers forever, especially since they became commonplace for things like Marvel Legends and even WWE. These are largely on ball joints, give me a bunch of them already. And not just alternate expressions -- a Bumblebee with a toy and cartoon head, an Optimus with a cartoon and comic head...
Just make them complete intact heads that fit on a neck ball that's standard across the line. No more of this Buzzworthy Army Builder 4-pack "masks on neck bases" silliness that leaves only one functional head at a time.
