I would bet against it. We haven't even built one of the key facilities to test the materials that we would hope to make a fusion reactor from. Once built, it will still take 20 years or so (as I recall) to come to some conclusions about suitable materials.

The sun is able to use gravity containment. Terrestrial fusion has to use magnetic and physical containment. The extremely high energy neutrons produced rapidly deteriorate common engineering materials. A replacement schedule is very difficult because of induced radioactivity, which means that the reactor cladding would need to be replaced by robots most likely.
