Overall Conclusions

CMB represents an incredible source of information on the nature of the Universe
Easy to link theory and initial conditions to obs
So far has told us a huge amount about initial conditions, content and fate
South Pole CMB pol expt lead the field in measurements of E-modes and limits on B-modes
BICEP2 has just deployed and should be able to improve the limits on inflationary tensor modes for the first time using polarization
Keck-Array is coming in the fall with further increase in sensitivity...
We have even more ambitious plans to make CMB lensing surveys in the future
