I just hope they don't limit druid shapes to just like bear, wolf and a cat xD
I'd quite like to see something similar to the variant rules that appear in Xanathar's guide. That once you see/have fought a beast you can then turn into it (assuming you can turn into a creature of that CR), would make it a little more interesting than bear, wolf or cat, and less confusing than a whole library of wildshapes.
