Nintendo will be showing a number of unreleased games at ECTS next month. For the duration of ECTS, 27th - 29th August, Nintendo will place a demo truck at the entrance to Earl's Court. The demo truck will feature Mario Kart: Double Dash, as well as other GameCube and Game Boy Advance games on over 40 consoles including GameCube, Game Boy Player, and Game Boy Advance SP.
Last year Nintendo did not take part in ECTS, but displayed games at Stuff Live later in the year.
