The new set was designed by production designer Michael Pickwoad, and the BBC have released this teaser photo — which appears to be the top of the main console. This will be the TARDIS interior for the Doctor and Clara at least through the back eight episodes of series seven in 2013.
This design — from what I can see of it — certainly is a departure from the Doctor’s current “desktop.” And it looks like the central console will be well-lit, at least. All that Gallifreyan writing is interesting, but I think there’s too much of it, and it’s too big.
In the words of the 11th Doctor (Matt Smith) himself, “I don’t like it.” But perhaps it will grow on me. Like coral.
