I'm just back from Antarctica, guiding a ski trip to the Pole, not climbing this time. I briefly caught up with Chris Stangl, with whom I attempted Tyree in 2008.
Hans only went to the west summit of Logan, not the main summit, so he has to go back to claim the 2nd7. Chris still needs K2.
Chris is already going for the 3rd7, as he has already climbed Kanchengjunga (2011) and Mount Shinn (2008) - with photos
There are some other issues with the peaks on the 2nd7 list, so the game is not over yet. Lots of secrecy and sneaking around been going on!
As for that PlanetMountain article, yes, there is now an argument for Mandala over Trikora, and no, Hans did not invent the concept of the Second Seven Summits.
