Any other game planned for after rockstarts L.A . Noire?

has rockstar got any other game(s) planned to start working on after everything is done and dusted with L.A. Noire like all the DLC and other bits and pieces? so are they planning to maybe do a game based around John Marstons glory gang days? or maybe a take on Sci-Fi like a free roaming space adventure, a starwars crossed with mass effect sort of theme but all out free roam and blood/ gritty violence and gore like red dead redemption or does anyone know any solid evidence on a new game they are trying to keep covered for later on in the year or beyond? if you know any ''REAL'' news please do share here lol :D lol thanks everyone! lol hahahaha lol by the way Red Dead Redemption and L.A. Noire was AMAZING :D lol
