  10. The Limits On Non-Gaussianity Departure from Gaussianity at 2th order: Y =YL+fNL(YL2-<YL2>) The simplest inflationary scenario predicts fNL' 10-1 WMAP: -58< fNL< -134

  11. Reionisation ClTexp(-2) on l > lrh ClT,TE,E,Bon l < lrh 0.20

  12. Open Problems: The Early Universe Initial conditions mostly adiabatic, Gaussian, scale-invariant, consistent with the simplest inflationary scenario, but that remains effective. Is the spectral index really running? What does it mean? Can we have a better limit on non-Gaussianity? Can we detect primordial gravitational waves? Can we hope to fix inflation into a coherent supersymmetric context?

  13. Open Problems: Concordance Model nicely 96% Dark, with Cosmological Constant Shall we detect WIMPS eventually? Should we repeat the Einstein greatest blunder? Log! An happy review of the Cosmological Constant Problem

  14. The CMB Future: Challenging The Concordance Needed: Imaging on all relevant CMB scales (Planck) Dark Matter & Energy Properties (Planck, SNAP,ALMA) TE modes cosmological polarisation, large scales (Planck) TE modes cosmological polarisation, small scales (Planck, Quest, ...) E modes cosmological polarisation, large scales (Planck) E modes cosmological polarisation, small scales (Planck, Quest, ...) B modes cosmological polarisation, if r>30% (Planck) More...a CMB polarisation satellite?
