Providing a delicious cupcake of credence to this rumour is one former Visceral artist's portfolio with a 3D modelled building from "London 1888".
The ex developer from Electronic Arts Montreal posted up an image with the filename '09_RipperBuilding3.jpg'. The artwork follows the heading "London 1888" which was the time of the Whitechapel murders in the prostitute-riddled London.
The Ripper is an Xbox Live Arcade and PlayStation Network title. EA Montreal had another proposed project in the works known as the 'Desertscape Project' according to the same former artist but it was cancelled in 2007.
The artworks are below with the first being from The Ripper.
