:::Bethesda's website says "The Showcase airs live around the world via Twitch and YouTube on June 14th at 7pm PST.":   The showcase is their pre-show conference.  The Independent article seems to suggest this as well with the sentence that follows the June 18 part: "The E3 showcase is the first time that the company has been to the gaming conference."  Nearly every other secondary source and official channels mention June 14 but don't mention June 18.
