I can answer at least one of those questions: The game's out in June, according to a post on the PlayStation.Blog. Producer Greg Phillips also confirmed a demo will precede the release, though specifics of what and when are still forthcoming. Lastly, they sent out the final box art, which you'll notice I've repurposed below for our own sinister uses.
Where's your interest level in InFamous at this point? For a refresher, check out the latest trailer we posted earlier in the week, which I have to say looks pretty slick. I love the graphic novel-style cutscenes. Now that Killzone 2 is out, this is probably the biggest first-party PS3 release on the horizon for the time being.
