Analysis of data of the short p-Pb pilot run in fall 2012, led to some intriguing observations by ALICE, ATLAS and CMS of ridge structures in two-particle correlations. In particular, the observed patterns are reminiscent of collective effects measured in Pb-Pb collisions. This triggered a lively discussion in the theoretical and experimental community. Various mechanisms ranging from saturation effects to hydrodynamical modeling have been confronted with the data. At the same time, the experimental collaborations at the LHC have continued the data analysis with the 2013 p-Pb run with interesting results.

The talk will give an overview of the findings in p-Pb collisions and their theoretical implications. Further, recent results of the ALICE collaboration exploiting particle identification will be presented which further assess the question: does it flow or not?.
