Huh! thanks for letting me know about that trailer. They look interesting; seems like they're pushing in more of an action game soccer-y direction and slightly less RPG-core RPG - though I guess maybe stats effect the block range on those hands they keep showing? I respect it as an attempt to change things up but I'm not sure I'd have a strong opinion without playing it.
God, I really hope we actually get a localization on that series again someday, it kills me that in this era we still have so many interesting games that never get localized
and yeah, I've only played the first two ds games!
