The 16 different block colors for hardened clay leaves a lot of texture pack makers with more blocks to work with which in turn more unique adventure maps that don't have to use the same blocks over and over again.
The most logical use i can think of is zombie knights for lack of a better word to counter the player on horseback. your ideas thoughts on the zombie/skelton horses that haven't been implmented yet?
If they can nail horses down i belive than can code the red dragon to move around blocks in the overworld. I really hope they end up doing something with the dragon egg even if it's just a animation that makes it move every once in a while.
The first time i saw a creeper was on my friends world and his texture pack made it look like a steve. so i walked up to introduce myself to steve and boom all my meager items were gone.
Lesson learned: don't trust a friend laughing in the background
Mine was when i first got minecraft i loaded my world and decided to go explore a mountian being a avid player of sneaky games my sneak button was always space for easy access so after i climbed to the top of this mountian i hit space and jumped off the mountian
