If they make a K3, it will be in the distant future, as in a couple of years before release AT LEAST. I hope it's made by Obsidian, since the plot, IMO, was much more interesting than that of K1's besides the good old K1 twist. If LA is making it, we'll have to wait even longer, since they're busy on the Force Unleashed.
