I wouldn't be too optimistic. The theory they are talking about is BCS theory. Most of the other high TC superconductors cannot be explained with it and high TC BCS superconductivity so far requires crazy environments with no clear path to making them easier to use. With the kinds of pressures required to make this happen, it's probably easier to just buy liquid nitrogen and use other materials.
