I really like the bird Minicon and his interaction with Optimus looks pretty cool with the wings and chest armor.
The current images, though, don't really fill me with confidence that the Optimus figure is all that great. But then again, this design hasn't really caught my interest across the multiple size classes so far, so yet another just isn't wowing me.
I also am liking the decision to make the Minicons partner-figures for the Autobots. And blue energy armor makes so much more sense than the orange...at least as far as the currently aired episodes are concerned.
But out of all of these TAV/RiD toys, I'll probably just get the Drift and Fracture Minicons that were previously only available as pack-ins with the Deployers.
