Not A Blog, the journal of author George R. R. Martin, mentions the unannounced Game of Thrones RPG that's known to be in development at Cyanide in addition to Game of Thrones: Genesis, their upcoming RTS game based on the A Song of Ice and Fire books (thanks Gamer's Hell). It's just a passing mention, but it does make it clear the game is a ways off:

(Just to be clear. This is the RTS game, designed and developed by Cyanide's studio in Montreal. A second videogame, an RPG, is also under development at Cyanide's studio in France, but that one won't be along for a while yet. The two games are very different, so please don't get them confused).
