New animations/sprites?

So I noticed Original Cuu Chulain and Medusa recently had their battle sprites and animations updated? And a quick glance over the list of units I have it looks like Medea has new sprites as well, though I haven't checked her animations yet. Is there a list somewhere of who all got updated like that, assuming those three are not all?

I definitely want to see all the new animations, I was just talking with a friend recently about how some servants had so much more love put into their animations than others, so some of the older servants getting attention is super cool.
