Xenoblade Chronicles Definitive Edition is going to feature a lot of improvements over the original Wii release, including better lip-syncing.

Speaking with RogerBase, Rob from the Nintendo Treehouse Team confirmed that the game is going to feature reworked lip-syncing for the whole game. Footage of the Future Connected epilogue showed superior lip-syncing compared to the original game, obviously, but it's good to know that the main game received a similar treatment.
