[From many - one.]

As I read the the original definition stands and the hew material makes it easier to identify reproductive isolates.

It's still a matter of them as can't interbreed are different species, just a better way to determine "can't interbreed"

At first I thought this was a stronger definition based on speciation at the genetic level, but I'm not so sure:

We define a genetic species as a group of genetically compatible interbreeding natural populations that is genetically isolated from other such groups. This focus on genetic isolation rather than reproductive isolation distinguishes the Genetic Species Concept from the Biological Species Concept. Recognition of species that are genetically isolated (but not reproductively isolated) results in an enhanced understanding of biodiversity and the nature of speciation as well as speciation-based issues and evolution of mammals.

I haven't digested the article yet, but this seems to be a whole new concept.

"It's still a matter of them as can't interbreed are different species, just a better way to determine "can't interbreed""

Just to pick nits, it is 'don't interbreed' not 'can't interbreed'. Your definition doesn't consider parapatric or sympatric speciation.
