Pff..! What sort of a comment is that?! First of all, "soon" can mean anything. Second, references are, as always, greatly appreciated! :-)

ehm... the reference comes from a recent talk by Lyman Page.
Concerning the 'soon'....it seems that they are writing up the
main papers, so perhaps end of the year ?

cheers

More to the point - do you expect anything important to change significantly?

I guess they will have better polarization results. sigma_8 may change a bit.
tau and n_s too...
Most interesting thing will be non gaussianity and the possible confirmation of the several anomalies...

Just plotted the 5 year power spectrum versus 3 year. Difference looks bigger than I expected.

Interesting, thanks! Looks like some change in some calibration(s)?

Thanks! very interesting...I would say beam calibration perhaps ?
I wonder how TE compares...

Yes, it's the revised beams. *Huge* difference -- much larger than anybody expected, given their original claims in the 3-yr release, I think. Essentially, from what I've seen so far, WMAP5 seems like a pretty nice bug fix, but not really a whole lot more.. :-)

FYI, we had two back to back workshops on early universe and non-gaussianity at PI. Most of talks are now available online. In particular Eiichiro gave two talks on WMAP5 results, that you can watch at: http://www.perimeterinstitute.ca/News/I ... p_results/

You can watch rest of the talks (mostly related to primordial non-gaussianity) through http://pirsa.org/

Might be worth taking a moment to remember the sorts of error bars we were used to looking at six or seven years ago. Pretty remarkable progress!
