Renember many years ago at Games Day some mock ups of some new Battle Fleet Gothic ships were shown and have been sitting around in the reserves for a long time. But the French GW site indicates the three new vessels for the Adeptus Mechcanicus, a light cruiser, cruiser and battleship will be released on: 06/08/2007 according to the site.

Here is the link to the site: Games Workshop France - Prochaines Sorties
I believe on the Warseer site there are photos of the mock ups, but obviously I can't post it here.

Great to see GW still cares for neglected but awesome game system! ^_^
