A wider variety of intricate Yoshida style art based weapons and armor? Yes please.
Chocobos in a variety of colors and armor since we'll be in the middle of a war (Wings of the Goddess/Tactics/XII)? Yes please.

But just random pets that really dont do anything, thats just a little too much of a me too thing. Sure, other games have great ideas and it would be awesome for Yoshi-P and his team to take inspiration from that, but vanity pets are a bit much. Now if they put an FF spin on it (used it to decorate your own personal area) then maybe.
