This looks to be our first glimpse of the next game in the Hitman series. Well, not the game, per se, more like the game's poster and promotional artwork.
It can be found on the website of Great Graphics, a design firm that's worked with Square Enix - the series' new publisher - before, on the upcoming Kane & Lynch 2.
Both these posters show a burning Hitman logo, the branding of publishers Eidos and Square Enix and, most importantly, that of long-time series developers IO Interactive. One also has 2011 stamped on it. Seems to suggest a 2011 release for the next
God of War
Hitman game, but since they're listed as poster concepts on the company's page, and not the final product, don't go holding them to that just yet.
