Hi - does anybody have a rough idea of the increase in accuracy which the upcoming ESA Planck CMB Probe will give us regarding the age of the universe? The combined results of WMAP, BABAR et al gave us an age of ~13.7 (+/- .2) *10^9 years. Ie: How much will Planck improve on this value and its error bars?

thanks, Gene
