... Exactly. More out than in is pretty much the definition of a "commercial" system, and since ITER isn't planned to be hooked into the grid, I therefore characterised it as "semi-commercial". If (and that's still a pretty big "if") it works as planned, and it doesn't leak alpha particles and tritium into the world, and doesn't suffer huge neutron bombardment degradation, it will simply be scaled up and be used as the pattern for DEMO / PROTO.
Then again, if Lockheed really can start churning out viable 100MW units on a factory production line inside a decade or so, all bets are off. No-one is going to be too interested in building expensive large-scale plants for anything other than research purposes if you can just order generating capacity off the shelf
