You may have thought that all the kerfuffle and fall-out from L.A. Noire devs Team Bondi, that Rockstar and Take 2 might steer clear of another stab at the crimey, nostalgy 'franchise'. You would be dead wrong.
Rockstar has answered the question... "Wot, no more LA Noire?":
"While there won’t be any more DLC or additional content for the current release of L.A. Noire
(we’re all too busy working on Max Payne 3
and other games to come), don’t count out the possibility of a new game in the L.A. Noire
franchise in the future. We simply have not decided anything. We’re all very pleased with how that game turned out and are considering what the future may hold for L.A. Noire
as a series. We don’t always rush to make sequels, but that does not mean we won’t get to them eventually – see Max
and Red Dead
for evidence of that – we have so many games we want to make and the issue is always one of bandwidth and timing."
