^I think they know fully well what they put or dont put in the series. They likely keep certain monsters off the radar to generate hype for their return in the future. People love Lunastra, and reintroducing her now would actually hype more people, same with Lucent Narga and a few others. That being said, since this is a celebration game, all monsters that we have up until now should really make that comeback, theres almost no excuse for it now at this point.
