Did theyreally need to make another pokemon movie

The level 50 one. -Wasn't aware there was a level 100 one. I usually let information like that surprise me.-

Fusion Flare and.....errrr...Zekrom's level 50 move, Fusion Bolt.

And as for shouri's question, there's no insight of what its 4th move would be yet.

All four moves have been known since the movie came out.
