Sooo... Not likely habitable. Unfortunately, no current planetary survey exists that can identify earth-like planets that orbit at earth-like distances around sun-like stars. Not even Kepler, which is itself considerably better than the radial velocity technique mentioned in this article, which can only find closely-orbiting planets around stars that aren't that much bigger than them.
The good news is there are a lot of sun-like stars, and it does seem from the Kepler survey that planets are pretty common. We just don't have the technology to find them yet.
