Peter Jackson wore this on a shirt in one of The Hobbit production blogs:
So it's definitely very possible that that's our first glimpse of what Smaug's going to look like onscreen.

I'm glad Peter Jackson and co. aren't doing a radical re-design (not that many probably expected them to, but still). =)
