Hmm... I don't see them going back to Dual Screen gaming tbh, since it's only logical to make a Switch like system with more power etc. (to ride on its success) than to revamp (/ change) the whole look & gaming experience and risk losing/ confusing customers, all for nothing.. Unless they have some plan already in mind, like both screens be used as one, and can only be split in two when 2 players want to play with each other.. while maintaining BC with the Switch library..
