There's been a lot of interesting progress recently using high-temperature superconductors that weren't available when ITER was being designed. This should make fusion a lot more attainable and practically useful. That said, I don't think we should count on fusion to get us out of this when renewables are a good-enough solution that's available now and they're cheap. (If storage is an issue, perhaps that means we should be investing in long-distance transmission lines so we can, for instance, power North America at night using solar panels in the Sahara.)
