Nintendo overtakes Sony's 'Gran Turismo 5: Prologue' at the top of the All Formats Chart as 'Mario Kart Wii' records the 8th biggest launch week ever in the UK. 'Mario Kart Wii' is far and away the biggest launch of any Nintendo published title. It's also bigger than the launch weeks of all 5 other Mario Wii games combined (Mario and Sonic at the Olympic Games, Super Mario Galaxy, Mario Strikers, Mario Party 8 and Super Paper Mario). Mario has performed heroically on Nintendo's next-gen format with Wii games featuring Mario accounting for 21.2% of all Wii units since the launch of the console in December 2006.
