I am limiting this prediction to mass-consumed applications of technology.

If we extrapolate (obligatory: http://xkcd.com/605/) present trends it seems that the platform of the future will be the web.

This will require fast internet connections on computing devices (whatever those will look like in 10 years) as pervasive as water and electricity in the rich world. And we are getting there.

So the language of the future will be based on this platform. The obvious choice then would be javascript. But javascript has a lot of problems so most likely someone will invent a language of the form javascript++ within a few years.
