-2016 holiday is the earliest, 2017 holidays is the lattest.
-Powered aywhere between vita and wii U, run games in a 640p screen(the patter for lots of ps360 games), 3D support.
-Keep a 480p second screen(touchable).
-Of course there will be exclusives(pokemon, AC...), but most of library will be shared with home console, including VC and indies.
-200$ at launch.
-desagree the name.
-The most important: The new kind of input(I agree that this time will be a input). They will improve the face tracker they introduced on N3DS, the tracker could read your face, so, blinking the eye, looking to the bottom screen, showing the tongle, smiling, or tracing your pupil to know where are you looking, could be used as inputs for gaming. (some possibilities: the nintendog mimicing you face movements, a new metroid where if you are looking to the upper screen, the controls respond as a side scroller, if you look at the bottom screen, the controllers respond as a FPS, or select something on screen by looking at it.).
They will market this functionality heavily, but wont be a great revolution(like 3D on 3DS)
