I disagree. They did find superconductivity in graphite grains at room temperature, and it is freakin' amazing. Next, someone will figure out why it happens, and figure out a way to make it happen more, happen in different stuff, or whatever. There's obviously a big leap between "we found superconductivity at room-temperature" and "we found a practical room-temperature superconductor", but it's also obviously a good step along the path.
