YES! This is exactly what I wanted. There's really been nothing but new Dragon-type Digimon since Savers ended, and in particular there hasn't been new Aquatic Digimon or new machine-type Digimon lower than Perfect in nearly decades. I guess wave 2 will be the other three fields. I also hope that possibly all the Olympus 12 are in this set as final Ultimates.
I suspected we might be getting a new "expansion-level" influx of new Digimon due to the card game being revived. There are over 1000 Digimon but not evenly distributed amongst the levels - with a lot of the recent ones in the past decade being Ultimate/Mega. It only stood to reason that eventually new Child/Adults/Perfects would be needed in a fairly large amount to keep interest in the TCG going for a few years.
Gogumamon looks like a pre evo for blastmon.
That it does. A few of these seem to be attempts to tie levels together. For instance, Ghosmon looks like it was created with the intent of creating an "official" Child-level for Wizarmon
and Bakemon. It's also by far my favorite out of this set.
My dearest wish is for Deep Savers to get a proper Ultimate-level Lovecraftian Digimon for Dagomon to evolve into (I really wish Dagomon had just been Ultimate level anyways considering how terrifying it looks).
I also hope the special eggs for Wormmon and Armadimon are split like V-mon's was to give them "normal" non-Jogressed Perfect and Ultimate levels - like JewelBeemon and Bantyo Stingmon being in Wormmon's path.
