Yes, that's right. A new version of Project Thundercloud fixing a few problems that have been pointed out will be released as the introduction of Project Shadowbox.
- The scene with Cheerilee will be reedited for accuracy.
- The scene with Dinky will also be reedited for accuracy.
- The audio will be fixed so that the dialogues won't be drowned by the background music.
- Some background music will be changed.
- The film will be faster paced by shortening the transitions.

A few changes to the animation will also happen, but only to match the animation of Project Shadowbox.
- As the aspect ratio changed from 16:9 to 2:1, most scenes will simply be reframed using a pan and scan technique.
- The night sky will be slightly different.
- The 3D scenes will feature Z-depth blur.
- The distance blurs will be hexagonal rather than Gaussian.
- The lens flares will also be different.

As for Project Shadowbox itself, the fan film will only be released in a single official version rather than the four I made for Project Thundercloud. The opening logos will also be slightly shorter.
