Predict the next "nostalgia" battlefield!

So, since we've gotten this battlefield where you steal from a mob to fight flans for an intentionally low drop rate as a reference to Final Fantasy IV, I thought it might be fun to speculate on what future battles of this nature might look like: how you might access them, what the fight will be like, and what the drop could be.

I still think the Final Fantasy 6 fight is going to be all Animated all the time, as a tribute to the Dragon's Neck Coliseum where you watched helplessly as your chosen party member forgot every skill and spell you ever taught them and cast poison and slow until being mercilessly mowed down by an inferior opponent.

For the Final Fantasy 9 fight, I'm thinking the entry item might be a little nod to one of the more memorable cutscenes in the game: after locus qiqirn enemies are added, killing several of them with a single use of Odin's Zantetsuken will grant a chance to obtain the entry item.

What have you guys got? I bet we can come up with some amazing predictions.
