Well its about time. So lemme guess, it should be 5 to 10 years before we'll see this used?
I'd say probably closer to 20-25 years before we see a controlled thermonuclear reaction used as a power source. There's a promising experimental design that's scheduled to begin production soon (ITER, will be built in either France or Japan)-- although construction could take up to 10-15 years and I assume that it would be another 10 years at least before we had a real working model.
