There will be no expeditions going up the Cesen route this year. Instead 5 expeditions will be taking the Abruzzi Ridge. Rob Springer mentioned this on his blog.
Field Touring Alpine must have changed their plans because initially he was saying that they were going up this route. Last year rock fall was a constant threat as the temperatures rose on this route.
Along with the 5 expeditions on the Abruzzi Ridge, there will be a new route pioneered on the South West Face of K2. This will be attempted by French Christian Trommsdorff and Russian Alexey Bolotov.
