The FFIX commercial shows Zidane chasing a shining coke bottle cap through Alexandria. Vivi and Garnet follow in pursuit. As the bottle cap passes by, the people and building transform to look all shiny and stuff (for example, Alexandrian soldiers get gold armor).

The FFX one just shows coke bottles and FFX collectible figures. I didn't know there had been one for FFX.

No pic, sorry.
