I saw images of the Switch 2 game boxes from the side, and love how the cover art wraps around. That looks really nice. I never did like that plain text for the Switch 1 cases.
I can understand Nintendo's challenge in branding. They want consumers to understand this is the new system and that its games won't play on the older Switch. This will be a bigger problem than you realize. Remember that parents with children have always been Nintendo's key audience, and even though we have been playing videogames for 40-50 years, a lot of parents out there have no clue how any of this works.
