Details of the interview (and a link to it) are at rampancy.net.
"The game centers on the story of Connacht the Wolf—a hero so great that he heralds in a new age for the world, the Wolf Age. Connacht's allies are none other than the very Fallen Lords from Myth: the Fallen Lords, when they were still champions of the Light."
So apparently there's more than just Damas working with Connacht. Myrdred is the next most likely candidate, and is there a third? Ravanna? The Faceless Man?
"...over 30 types of units; many of them familiar, plus a number of new ones—from Berserks to Myrkridian Pack-Mages, Trow Iron Warriors and Ghol Priests."
I'd guess that Pack-Mages are Myrk giants who focus more on magic and less on muscle. As for Ghol Priests? Looks like the Stone Cold Ghol Shaman from the Fear documentation is finally getting his place in the sun. :-)
Also, Phish zoomed in on one of the interview's screenshots and confirmed that Myth3 has Thrall. (That was unexpected, huh?) So an appearance by the Watcher is a good bet...
