Nintendo was full of non-answers for Luigi's Mansion 3 at E3 2019. In an interview with GameXplain, Nintendo's Nate Bihldorff did confirm that the game won't support amiibo. As far as Nintendo Labo VR support, Bihldorff had nothing to say. The same goes for DLC, so we have no idea what's going on there either. We'll just have to hang tight on those fronts and see if Nintendo has anymore concrete answers to share moving forward.
