I wonder how the specs compare to the Wii U so I can know what the expect from the next Zelda game.
Ars is estimating (based upon it using a Tegra X2) that it will probably be slightly better than the Wii U at 1080p gaming, but weaker than the PS4 and X1.
The controller sure look small, I assume they will have some kind of motion detection like the wii's controller?
It could use them, as you could always disconnect the Joy-Con controllers from whatever they're connected to, but requiring motion controls seems like it would really hamper the on-the-go playstyle that they're trying to push. Just thinking about their video, it'd work for the at home scenarios that they showed, but most of the outside ones would probably not work well.
The two problems are: space for movement and screen size. If you want to play something like Just Dance, you're going to need space, and some on-the-go scenarios simply don't afford that. That also gets into the other problem in that Ars estimates that this is essentially a 7" tablet, which means that you really can't distance yourself that far from it and actually use the screen.
That actually made me think of an interesting point... games designed for small screens are generally
not the same as games designed for larger screens (i.e. TVs). I'm not talking about mechanics like actual platforming vs. endless runners, but rather things like UI elements. Referencing my statement of "actually use the screen" above, I wondered, "Will it be easy to spot certain UI elements on the screen? Will they have to adjust the design based upon whether it's docked or not?"
