You're right. The gaming opportunity for Nvidia is groing to at most grow at a ~20% CAGR through 2022, and this is largely being driven by the international markets. The US gaming GPU market is only growing at low-single-digits for the foreseeable future. The autonomous driving and datacenter opportunity are a completely different story. The datacenter business is already growing at >100% y/y and this market has only just started to kick off about 6-9 months ago. How big it will be in 5 or 10 years is still up in the air, but it looks like it will be massive. The auto opportunity hasn't picked up yet but it's becoming increasingly clear GPUs will play an integral role in any level 4 or level 5 ADAS vehicle. Both of these markets were a completely neglible portion of the NVDA's story just two years ago.

Today, with the stock up more than 250% in the last 18mo., the implied market size (and market share) estimates in the stock are already pretty ambitious. In my opinion, they're not too ambitious, but the question now becomes, when will it become clear that they are conservative? What will it take? SoftBank has a long time horizon, they're comfortable waiting for when this happens, whether it's in 4 quarters if datacenter growth grows from even these remarkable levels or in 4 years when the autonomous driving market with be beginning to take shape...

The Switch is highly profitable for Nvidia. They could be looking at upwards of $100 million a year in profit on the Switch, and upwards of $400 million a year in revenue, almost doubling the size of their Tegra division. $100 million in profit and $400 million in revenue for a company that does just under $7 billion in revenue is 2016 is very significant.

I have no doubt it's significant amount of money, but still nowhere near to justify growth. And even if it's one of factors it's still very small one since both big consoles use AMD hardware and in next 3-4 years there not going to be another one.
