The de Sitter vacuum might be more unstable than previously thought. Also the CMB data gives a Hubble parameter H = 68km/s-Mpc while galactic red shift, some .5 by or more after the CMB surface of last scatter, gives 74km/s-Mpc. The vacuum energy density might indeed be increasing or not entirely stable. When the idea of phantom energy and big rip came out I thought it was preposterous, but with observational data and theory suggesting instability of the dS vacuum big rip is a distinct possibility.
