That can synergize with GPS. Many OEM Nav systems in cars these days do something similar in tunnels, where GPS signals are unavailable.
But if gyroscopes became precise enough, I can't think of a reason for needing GPS anymore, can you?
I don't think the future is GPS at all. I remember reading a while back about a researcher who was working on developing tiny optical gyroscopes that were ridiculously precise, the idea being that you can calibrate their position once and after that all future locations are determined simply by integrating the acceleration of the gyroscope. It would work in places that GPS can't (like caves). To me, that's really awe…

Dead reckoning is subject to cumulative errors, so that would have to be REALLY accurate.

The key line in this article: "The disadvantage with this is that you wouldn’t get your location in real-time – it’s processed later." The viability of this seems tied to how long 'later' is. Most consumer uses of GPS require quick response times or you'll see a huge dropoff in usage.
So, I could see there being some consumer uses for it, if you could demonstrate that the power saving was worth the wait.
This is why your iPhone or Android is a hundred or even several thousand times faster to "recalculate" a new route when you take a wrong turn than your trusty, old Garmin. That's also why if you get lost in the middle of nowhere w/out cellular reception, you'll be hoping your old TomTom is still in the glove box - the maps and routing algorithms are all stored on the device itself (though this means the data on it gets outdated and you will need to update it, often for a price).
I thought this was going to suggest cloud route processing, like Apple Maps/Google Maps/Nokia Here where the GPS is done on the phone, but the routing is done in the cloud.

Doesn't google maps allow downloading of data to the phone for use without internet?

Keep in mind that as precise as gyroscope can get, they could be susceptible to shock (if you drop it on the ground).
But I am interested in seeing how it could develop into
