The key part is "the only one we know". Jordan has confirmed Min's not unique, or at least she won't remain unique for much longer (perhaps for the whole series, but her Talent won't be unique in the next Age is what he meant).

It appears Jordan had very good reasons to multiply the other "oracular" Talents. He needed Egwene to get trained, thus the other Dreamers (Perrin rather had Hopper). Nicola was a kind of red herring. She's made prophecies, only one of which in effect counts, and it's the one no one but the readers know about! The others weren't believed, and we don't know what they were, and now she died before proving herself. Elaida's foretellings she largely kept secret.

As for Elyas and Noam... the purpose of Noam was to be a false threat over Perrin for most of the series, and now he's understood this, and that Noam chose to become wolf for good. As for Elyas, his purpose (beside guiding Perrin early on.. but Perrin is beyond his guidance now) appears to be to provide a POV character with the wolves in the LB, perhaps because Perrin leading the wolves will happen quite late, and first he has more to do with his human armies.

As for Min... well... there appears to be no plot reason not to make her Talent unique in the series. It would be weird for another character to have it, and not to get involved... and yet, it would be as weird, and it would have gotten old, to have another regular with this Talent (and there's something like too many Viewings... they're not rare like Foretellings.) All three of Rand's women now have their unique and significant talent: Min has her viewings, Elayne makes things, and Aviendha understands the purpose of things.
