What is Crysis Warhead?

What's up with all of the secrecy over at Crytek these days? First, they announce that there will be no 1.3 patch to the game, which obviously set some people into panic mode. Now they've casually dropped this image upon us.

I'm going to go out on a limb and guess that my original guess is correct, that they are just skipping any further 1.x patches and moving straight into 2.0. What exactly is all of this Warhead that we're seeing? I'd guess an expansion pack.

So the bottom line is that you're likely going to have to drop some extra cash on this expansion if you want any further updates. Then again, if you're a fan of the game, you'll probably pick it up anyway.
