Nintendo have officially confirmed that their E3 press conference will begin at 9:00am on June 5 (local time) in Los Angeles. It is very much the expected time as Nintendo have kicked off the first official E3 day with their press conference for the last few E3 events. Both Microsoft and Sony are holding their events on the day prior (Monday, June 4).
We expect the final specifications and details on Wii U to emerge from the presser as well as new games for both Nintendo 3DS and Wii U (with a large number likely playable at the show). The Nintendo press conference will kick off at 5:00pm BST (June 5), so make sure you get home in time.
