Nintendo president Satoru Iwata has given the most definitive indication yet that the platform holder will not develop for rival systems, stating that it would only be a strategy he'd employ if he did not care about the company.
Speaking to CVG contributor Steve Boxer, Iwata insisted that his job is to secure long-term prosperity for the company, rather than jump on quick fixes.
"If I was to take responsibility for the company for just the next one or two years, and if I was not concerned about the long-term future of Nintendo at all, it might make sense for us to provide our important franchises for other platforms, and then we might be able to gain some short-term profit," he said.
"However, I'm really responsible for the long-term future of Nintendo as well, so I would never think about providing our precious resources for other platforms at all."
Since the launch of Wii U, various executives within the games industry have suggested Nintendo could restore its fortunes by developing software for other platforms.
In June, the respected Eidos life president Ian Livingstone said Nintendo should have its IP on every platform.
As well as branding this as a fast-buck policy, Iwata said such a switch would remove one of the company's pillar assets.
"What I believe is that Nintendo is a very unique company, because it does its business by designing and introducing people to hardware and software - by integrating them, we can be unique. And because we have hardware and software developers in the same building, they stimulate each other," he said.
"And those kinds of conditions have enabled us to create something that no other companies can create. Those kinds of backgrounds are there behind the fact that such a number of great Nintendo franchises exist, and those great franchises always shine for people around the world."
Since its November 2012 launch, Nintendo has been challenged by the Wii U underperforming globally at retail. In July, the company revealed that only 160,000 units had been sold around the world in three months, which it blamed on "the release of few key first-party titles".
As well as the firm's initial struggles with HD development resources, Iwata said the company is also challenged by the expectations of its audience.
"I would say that the people's expectations about what will come next from Nintendo is becoming higher and higher," he said. "So we are facing more challenges than ever - that's true.
"But it's nothing new for Nintendo. Nintendo is a company that has never stopped progressing, and when it comes to the fan-base, of course, we have to sustain that, but we are always trying to expand that."
Nintendo's first financial quarter (ending June 30, 2013) resulted in net profits of 8.6 billion yen (£57m / $88m), thanks largely to the strong performance of 3DS.
