Is the K-5 a ten-year camera?

Having purchased one recently, and not wanting to buy another DLSR for a long time,
5 years seems like a pretty reasonable useful life for a K-5.

But what about 10 years? Will this be the kind of camera people become attached to? Will it stay reliable for 10 years? Will people still want sharp, properly exposed photos then any less than now?

I have an idea that the K-5 will become something of the digital K1000.
