Visited battle.net for the first time in awhile the other day and across across the following video.
Of particular interest is the following image, which was posted individually at the Starcraft Legacy site.
Looks like Kerrigan's post-deinfestation Zerg dreads are gone, although her hair seems colored somewhat differently (it's duller and more brown/orange than red) and in a different style. She is wearing Ghost armor, though. Some of the early discussion of "Heart of the Swarm" described Kerrigan "building her power through mutations," but at least in that image, that does not appear to have been the case.
(Let's hope it stays that way. Her turning back into the Queen of Blades would be entirely too GrimDark and sad.)
The scuttlebutt about what "Heart of the Swarm" is going to be about involves Kerrigan building her power and regaining control of the Swarm. The image looks like she's taking control of an Ultralisk, with what looks like some Zerglings nearby (all those little eyes beneath the Ultralisk).
My first attempt at Walk and Talk
