Microsoft has sent out a "save the date" email announcing its major events leading up to E3 2010 (June 15–17). The first event, the "World Premiere 'Project Natal' for Xbox 360 Experience," is open to all ages and will be held on Sunday, June 13 at the Galen Center in Los Angeles. No further details have been provided, though Microsoft announced earlier this month that it's bringing "the full lineup" of Natal titles to E3.
The following morning, on Monday, June 14, Microsoft will hold its annual E3 media briefing at the Wiltern Theater. The event will be restricted to ages 18 and older. With the media getting a taste of Natal the night before, it should be interesting to see what Microsoft has up its sleeve for the actual briefing. Expect more details on both events in the near future.
