Who's talking about ITER? Compact spherical tokamaks are racing ahead, due to the scaling law P ∝ B^4 * r^3 (oversimplification, but those are the proportions). High temperature superconductors have increased in current density and come down in cost so much since ITER was specified in the 90s they couldn't have anticipated the leapfrogging currently going on. STs can iterate faster for the same because their magnets are more powerful, so can be more compact for a given target power output. While ITER won't ignite for decades, Tokamak Energy and the like have already built several experimental reactors and Q > 1 in the lab within 10 years.
