I ordered mine little time ago, so it must be stuck in the current christmass mail somewhere.
For VOl2. I am expectig to see:
Aeris
Vivi
Tidus
Squall(leonheart)
And maybe Rikku of ffx-2 or the new female of ff13.

By the way wath about the other ff7 articulated minis?
I preordered Cloud and Aeris and there is Clouds Motorbike coming soon too.

EDIT: After seing the VOL2: oh great they putted tifa instead of Aeris there <_< ,

well if they make a 3rth vol I hope they make Aeris in cc style.
