2011, a case i've made before. It fits in with their strategy of upstreaming, of gradually building the blue ocean into something more complex (of raising blue ocean customers, as opposed to trying to fight into the red ocean)
They'll pursue a 3rd-pillar strategy with the Wii's successor for a time, so as not to cut the Wii's legs out from under it, but i see no reason for Nintendo to hold on to the Wii for an incredibly long time. Equally, i think the power of momentum in between generations should give Nintendo an edge, and that they will win the next generation unless Sony or Microsoft does something to change the rules of engagement, as it were.

Monster Hunter: pissing me off since 2010.
