Nintendo is on the brink of something incredible — or total disaster

The gaming world is abuzz about the official unveiling of the Nintendo Switch, the company's crazy new hybrid portable/TV console, which will launch for $299 on March 3rd. I'm excited, you're excited, we're all excited.

But if I'm Nintendo (and I'm pretending I am for a second), I'm feeling more than excitement. I'm feeling nervous. I'm feeling scared. Because in a very real way, this is a make-or-break situation for Nintendo. And depending how the Switch goes over with consumers, it could mean the end of Nintendo as we know it.

It's not that Nintendo is at risk of going out of business any time soon. Nintendo has over $5.7 billion cash in the bank as of its last earnings report, plus billions more in other assets. That's enough to keep the lights on at Nintendo for the foreseeable future.

It's really that, after a year of disappointments, Nintendo needs a hit — badly. If it doesn't deliver the goods with the Switch, Nintendo's investors are likely to pressure the gaming legend into shifting focus away from its own hardware, and towards making more software for smartphones and tablets.

Worse yet, investors are already bearish on the Switch: When Nintendo debuted the first trailer for the console, its stock tumbled. And now that the official details are out...it's tumbling even further.

Gamers are excited, but most analysts are concerned that the Switch's core gimmick, a tablet that can hook up to a TV, isn't going to be enough to set it apart from the more powerful and well-established Microsoft Xbox One and Sony PlayStation 4 gaming consoles.

The bottom line here: With the Nintendo Wii U flopping, and the long-awaited "Super Mario Run" for iPhone making way less money than expected, Nintendo is running out of breathing room in the market. And while the company has long found success by ignoring the conventional wisdom and going its own way, Nintendo is only as good as its latest hit.

The problem

The problem is that Nintendo is coming into this from a position of weakness. The Nintendo Wii U, the Switch's predecessor, was a major flop, selling only 13 million units in its lifetime — compared with the admittedly once-in-a-lifetime smashing success of the original Nintendo Wii console, which sold 101 million unites, or the Nintendo DS, which sold 154 million unites.

The Nintendo 3DS, the company's current handheld system, has been a more reliable performer in the choppy waters, with more than 60 million devices sold. But as the Wii U has floundered, it's dragged Nintendo's overall revenue down with it. As a result, Nintendo stock has been kind of a roller coaster ride the last few years.
