Ubisoft has officially announced Brothers in Arms for the Wii (They also announced it for the DS as well):

Brothers in Arms: Double Time promises to offer 31 playable levels, next-generation artificial intelligence, and Wiimote controls for both shooting and squad management. Brothers in Arms DS features stylus-based controls, detailed 3D graphics, drivable vehicles, 16 missions, and a redesigned multiplayer experience.

Multiplayer and 31 levels sounds pretty good to me!
