I suspect they will continue to trounce fission and fusion for a long time, at least until there is some some technical innovation in transmission and distribution.
Transmission and distributed generation accounts for half the cost of electricity. The question for our electricity future is distributed versus centralized generation, and distributed will probably win.
So distribute fission and fusion, overcomes much of that. And distributed solar and wind needs backup which is usually fairly centralized. Unless you want to spend 3-5 times as much for your energy to buy batteries.
Fusion needs to be distributed well away from population centres. Until we've had enough contained failures of the "intrinsically safe" reactors to be convinced that it's actually true.
