E3 2018's briefing schedule continues to come into focus, as Nintendo today announced the date and time for its big show. Nintendo's briefing, which will take the form of a pre-recorded video instead of a live broadcast, will air at 9 AM PT on June 12. That comes out to 12 PM in New York, 5 PM in London, and 2 AM the following morning in Sydney.

Nintendo did not provide any specifics or any teases about what will be in its E3 2018 briefing, but you can be pretty sure that the new Smash Bros. for Switch will play a big part. GameSpot will bring you the live broadcast to watch and ongoing coverage of the show with a live blog, news stories, and videos for all the major announcements.
