It seems unlikely to have much impact, but an influential shareholder is asking Nintendo to go mobile.

Previously managing the $3 billion DKR Soundshore Oasis fund, Seth Fischer now runs his own $200 million hedge fund.

He's written an open letter to Nintendo (as seen by Reuters), arguing the company is losing relevance in the market.

"Nintendo needs to embrace this thematic change in consumer demand, behaviour and expectations to stay relevant," he claimed.

Focusing on mobile, he added, "As the holder of what is arguably the largest library of casual games, Nintendo is well placed to make an immediate entry into mobile".

That's an interesting definition of "casual games", especially in the context of the dominant free-to-play business model with which Nintendo is yet to experiment.

Yet Fischer's wider point is something Nintendo CEO Satoru Iwata is likely to agree with.

"It is readily apparent that the standard elasticity of demand principle no longer applies in the consumer entertainment market when access requires the purchase of a physical product," he said.

As many have argued, even if Iwata - who is adamantly against mobile games - was to leave, it's hard to see the style of games Nintendo has built its reputation on easily porting to mobile.

And, as Nintendo recently announced, it's looking to move into what it calls its "Blue Ocean expansion" of non-wearable health hardware/software integration - something I've half-joking could be the 'Nintendo toilet'.
