Conclusions We are close to the first physics run of LHC. The next few weeks must be used to complete all preparatory work and to refine details of the analyses for the new initial scenario of 7 Te. V. Expectations are for months of operation at 7 -10 Te. V with the goal of collecting a few hundreds pb-1 of integrated luminosity. CMS is in an excellent status to produce good physics results from the first LHC data. A new era of discoveries is just in front of us. I. Golutvin and T.
