Nintendo normally do this summer tour where its just some big publicity extravaganza but this year it look promising.
THE NEW ZELDA WILL BE PLAYABLE, THE FULL E3 DEMO. oh yeah and nintendogs :P
basically nintendo tour up and down the country (UK) with the above and other new titles to play, plus theres always that man in the pikachu costume to kick in the shins then run away from.
