Planck 2013 constraints on inflationary models and plateau potentials

[Chronos]

Two CMB b mode polarization experiments are currently underway - EBEX and POLARBEAR.

From people that I have spoken to that work on PLanck they don't expect to see the B mode because its not designed to detect it. They hope they will get lucky but no one is betting on it.

Yes, this is correct. A rather high tensor amplitude is at the very limit of detectability of the instrument, but the simulations which say that don't take into account realistic systematic errors or the problems of component separation. So a detection of the B modes would be exceptional indeed.

What I was mostly referring to was the E-mode polarization, which Planck should be able to detect at a higher precision than previous experiments. While this is a dirty measurement of the tensor amplitude, it should provide at least some improvement in the constraints.

Andrei Linde strongly criticizes "Inflationary paradigm in trouble after 2013", in this talk.

Do you know when we can expect from results from these?

The first science run of EBEX was launched in late December 2012. POLARBEAR became operational in January 2013 and CMB polarization measurements are scheduled to begin in April 2013. No schedule for data release has been announced for either project, AFAIK.
