Yes, Ghost Squad has a dual wielding feature, if you accept 'just playing the two-player game by yourself' as a kind of dual wielding. It looks fun, however it's achieved. It also has a number of other newly-announced features that may be of interest to light-gun game enthusiasts.
For example, you can turn the cursor off. Since the Wiimote is not exactly a light gun and its pointer doesn't always move as quickly as your hand, the game displays a cursor by default. But you can turn it off for point bonuses and a more authentic gun game feeling.
Second, to combat the extreme brevity of the arcade game (as with all arcade gun games), Ghost Squad features a level system that changes the appearance and enemy layout of the levels as you replay them, gradually increasing the difficulty of the game.
