I had no idea it was getting another makeover. Was there a prior announcement?
Anyway, this image was posted on BBC America's Doctor Who website as part of their "The Snowmen" gallery
I did say it was a glimpse.
From the looks of it, I would say that what we are seeing in the image is the part directly above the console. Also, note the Gallifreyan symbols.
BBCA has have a separate article about the new control room here
, for anyone who's interested. In the article is Matt Smith's reaction to the new set:
“It’s sort of like getting a brand-new sports car. It’s always a bit exciting.”
