Wendelstein and ITER are supposed to verify whether it's possible to generate net power… with improved designs. So, assuming Wendelstein works as hoped, we will, in a few years, know whether we can start planning an actual fusion power plant (as opposed to a net-negative research reactor). Then we will need to actual design and build one. If we're lucky, we'll see the first pilot plants in 15-20 years. So, we're on the same level of "fusion practicability" as in 1960.
