Ignoring, for the moment, the fact that it is not in widescreen and lacks opening animation, consider the following facts:
1. The storyboard is by Yuyama Kunihiko - he usually handles the storyboards of the movies (except the shorts) and a few special episodes (EP001, AG001).
2. The director is Yuyama Kunihiko - he usually directs the movies (long and short) - neither Hidaka Masamitsu (former director of the TV anime), nor
Sudō Norihiko (current director of the TV anime).
3. There are executive producers, only found in movies (long and short), and, they are Kubo Masakazu and Itō Kenjirō (same as M9).
4. It is animated by Team Koitabashi (i.e. the production manager is Koitabashi Tsukasa) - they have done the movies (excluding shorts 1 - 3), the Winter Vacations (except the first one), Crystal, Mirage, and some of the side story episodes.
5. There are music producers: Shinohara Kazuo and Saitō Yūji (same as M6 - 9). Music producers are only found in the movies (long and short). However, this is perhaps because the music is all-new (as with the movies).
6. There are special thanks for the Pokémon Mystery Dungeon staff - in contrast, no such special thanks for the Pokémon Ranger staff in AG155 or AG171. Special thanks are, however, normal in the movies (long and short).
Only point 4 applies to Mirage. None of the points apply to the ANA shorts. Points 2, 3 and 5 also apply to 3D short 2; points 2 and 5 also apply to 3D short 1.
