When we heard that Ubisoft would bring Splinter Cell: Blacklist to Wii U, few details were given other than the day-and-date release date with other game versions and brief mention of GamePad features. That last bit was not an understatement, as evidenced by this trailer.
The controller will offer weapon/gadget selection, of course, as well as the option to tap your marks for execution. Using the GamePad's gyro for the spy cam and drone looks like it could be problematic from a precision standpoint, but we'll see. Blacklist is out on August 20 in North America and August 23 in Europe.
