First off is the Codex cover. Unsurprisingly, it's awesome.
The other big pic is the Wraith Knight himself.
It's big & badass. I really look forward to seeing how people will pint it. Also, just look at it compared to the Riptide. Here's a shot I found comparing them side by side. It looks to be about 30% taller which means it'd be around 9-10".
I'll be interested to see its stats, and its price tag. Given the size I'd wager it'll cost about the same as Baneblade.
