It is - of course - premature to say that Nintendo will win Gen 9 since we really don't know what they have planned. Iwata has hinted at a number of things, but hasn't been concrete on much at all. Some things we need to know:
-What is the QoL product?
-What company does Nintendo plan to acquire?
-What will be the impact of Nintendo's merged home/handheld hardware divisions?
-Will the QoL product link with the game devices?
-When will this Gen 9 product launch?
-What is the fate of Wii U?
I can see a best case scenario where Nintendo launches a new product next year which becomes the next big craze like Wii was, or even iPhones. They buy out a respected software maker like Square Enix. They launch a sleek new system with state of the art features in 2016 that has lots of processing power, is launched with lots of cool software and is associated with their hit QoL product so people want it like iPhone owners wanted iPads. But this is all speculation.
I only hope that Nintendo is really planning this out, because they really dropped the ball on Wii U despite lots of time and money available to them. Having a unified OS for their future products could potentially speed up software development, but I wouldn't say it would be a huge factor for winning the Gen, in and of itself.
