Right after you finish tuning in to our live blog of the Sony E3 09 press conference on Tuesday, June 2 (11:00 AM PST, 2:00 PM EST, 7:00 PM BST), you can head to your couch and watch it from PlayStation Home, confirmed James Gallagher of the European PlayStation Blog.
"You will be able to watch the SCEA press conference in Home, in a new space called the Presentation Podium," writes Gallagher. "We’re still waiting for confirmation of when [the video will be available]."
Reportedly, the video will arrive in Home a few hours after the conference, so you won’t have to wait too long to see all of the Sony happenings for yourself from the comfort of your home — PlayStation Home, that is.

UPDATE: This appears to apply to both European and North American regions.
