Ishibumi made lots of tweets concerning the names. Most of it are already known by older fans but not by the new ones. That's why he retweeted it.

The Gundam name combinations are already on the trivia pages of the current Yondai Maous, the three descendants, and Millicas.

The new ones are
 * Grayfia = Glaceon + Leafeon
 * Extinguish Star is something something about a specific Mega Garchomp. Still trying to figure this one out.
