Microsoft has booked its usual LA haunt, the Galen Center, for an event on June 10. Neowin contacted the venue and discovered the booking, which suggests that Microsoft will hold a pre-E3 press conference the day before the show begins.
This isn't a surprise – Microsoft always holds a pre-E3 event at the Galen Center – but the company has yet to announce this year's iteration. This event follows very shortly after the May 21 event at which Microsoft will reveal the next Xbox. Presumably we'll get more detail on that system and new game announcements at the E3 event. Or we'll be tricked into some avant-garde circus performance.
