We really don't know much about Nintendo's new hardware. It's codenamed NX. It's from Nintendo. And... well... That's about it, really. However, Nintendo president Satoru Iwata recently offered what could be vague hints. Or not.
In an interview with Nikkei, Iwata briefly mentioned the hardware, saying he wouldn't go into particulars about the NX. "However, if you only expand upon existing hardware, it's dull," Iwata said. "In some shape or form, we're always thinking about how we want to surprise players as well as our desire to change each person's video gaming life."
That's not much! Rather vague. So take that for whatever it's worth. I'll take it for Nintendo wants to surprise us again.
