There will surely be more Spec Ops games, but they certainly won't involve Walker and they probably won't have a similar storyline (I do think they would use a lot of elements, however, mainly the focus on morality).
I do not beleive this is exactly true, if i recall a recent interview with the writer this is only a possibility not confirmed its up to the player to take what they will from the game
