Switch will have more crossover with the PS/XBox audiences than the Wii U or 3DS did IMO. Those were basically strictly "Nintendo boxes", Switch can be more. Doesn't mean it's going to be some radical cross over, but definitely more than in the past.
Switch has more appeal to a general hardcore gamer than either the Wii U or 3DS did.
I think the sales of software on Switch will be more akin to the N64 too where other genres like shooters, action games, sports games, and so on were able to do well, it wasn't just all party/dance/fitness games + LEGO and Nintendo stuff.
