>>49576752From the little information we have to go off of, Centro (a very dubious source of information) made a post summarizing everything they knew about PLA at one point, including a ridable ursaring evolution, and forms for Dialga and Palkia. Apparently, this same source mentions that they're shooting for around 400 pokemon in the game, a similarly sized dex to the national dex of gen 4. If that's true, the dlc would add around 200 new pokemon, which seems like a lot considering the updated animations they'll had to have gotten, but I hope this is the case
Khu teased information with images of Palmer and Looker before eventually saying that Legends will be getting DLC, whether this is literal, in that we will be seeing these characters or their ancestors, or figurative, in that something about these characters relates to the DLC, or if they're teasing something else entirely is unknown.
However, I like many others feel that a battle facility of some kind makes sense for a post game DLC, and Ingo being a part in setting it up sounds like a fitting conclusion to his story, and if that's the case seeing Barry and Palmer's ancestor would make lots of sense, Barry is a main character and almost everyone else has ancestors in the game but him. I expect the addition of a battle facility/frontier, alongside a new map and maybe 5/6 new Hisuian forms/evos
Looker is also interesting, he's another important Sinnoh character with no reference in PLA, maybe another new area, a like 3/4 hisui mons, and a post game story?
