Yes, this seems to be in a pre-prototype stage. That means it can go either way, from "ready in 5 years" to "needs 10-30 years more materials science" to "does not work after all". What you really want is a prototype that has run at least to the first maintenance interval point, i.e. several years. Before there are too many unknowns.
