From the video, we see that Terra snaps on from the waist and there are several different poses shown.

1.) Terra holding a sword with her left arm behind her standing up.

2.) Terra sitting inside her armor with her hands on the controls.

3.) Terra reaching out with her right arm standing up.

These will all likely either be included in a single version or there may be a premium/special edition version that includes all the variations at a higher cost. 
Other than Yoshitaka Amano was involved in the statue's design, little else is known about the figure such as the release date or price but we're guessing it will be at least a couple of thousand dollars. We'll provide more updates as it's released.
