Nintendo will offer a conventional presentation for Switch in January. The Big N should detail in that event commercial aspects of Switch (price, initial line up of games and accessories) and maybe they could concrete some points about the hardware.
According to Venturabeat, Nintendo Switch would mount Nvidia Maxwell technology for its graphics to the detriment of Pascal tech, the new Nvidia’s solution for graphics introduced this year.
Maxwell would be powerful enough to show acceptable graphics in a portable system with console capabilities. Obviously, Switch is not going to be as powerful as PS4 is. Nintendo does not need that horsepower to create satisfactory games in the tech side.
