So, outside of a proper datamine, what are we still missing?
Unless someone gets an early copy of Sword, we won’t know they typings/stats/moves of its exclusive Pokémon.
But we’ve got a good idea about most of the Dex at this point, as well as decent hypothetical stats. We’ve seen most (all?) Gigantamax forms, either in game or through the guide leak. We also know the gym types as well as the big story points.
I guess we can ask the leaker for some of the NFE Pokémon stats, and a few more TM/TRs but unless I’m missing something, it seems like we’ve exhausted most of the info you can pull from just a play through.
Primarily things relating to old Pokemon. Stat buffs? Movepool updates? New abilities? Have any moves or abilities been changed in any ways we haven't seen? I feel like there is still quite a bit we have not seen. Maybe its stuff that exists below the surface where a casual play through might not catch, but its enough that requiring dedicated research into every 1 and 0 would be warranted.
