I'm curious what the on-deck titles might be.
Assuming actual games and not software, the 3DS had Face Raiders, Streetpass Mii Plaza with Puzzle Swap and Find Mii, and the AR games. . .so I guess that counts as 3-4 depending on perspective.
The Wii U didn't have squat as far as I remember, though.
"Interact with your game on the go" is worrying to me, too, but I wouldn't worry about outright losing handheld franchises if Nintendo only makes one system so much as their just only being playable at home or something. Or since Pokemon Company is on board and they seem adamant on only working on handhelds, perhaps some games will be fully portable and others won't, allowing 3rd Party devs to make ports of current gen games with mobile functions when not docked while Game Freak and others make games that function fully in and out of the house alike.
Base price is a little higher than their previous discussion was implying, especially with the bundle, but I suppose it remains to be seen what the system actually offers.
Color scheme of the box sounds Wii-ish.
