Nintendo's philosophy has always revolved around the family friendly experience and such a fact has lead to the company's slow progression into the online arena. The quality of experiences within the living room space have been a greater priority than the rising concept of global gaming.
With all of that said, the current expectations of your average multiplayer fanatic will present both new opportunities and challenges for the company. And looking at how the company is making strides with online offerings such as Miiverse it will be interesting to see if they join Sony and Microsoft in the basics of their approach or expand the established family theme in a way similar to facebook. Either way we must prepare for Nintendo to take on the world of connectivity in providing their next great multiplayer concept.
