I didn't get it, but a friend of mine picked it up on release. I like what I saw. It's basically an extension to the original, but with enough added to it to make it feel fresh. And I didn't see the whole game yet (saw a bit less than half), but what I saw had really nice humor, better atmosphere and there's some very nice puzzles. Seems well worth getting, especially the PS3 version since it comes with the PC version for free.
