The business card already sort of gave it away, but Kojima confirmed on his English Twitter account that he will be attending E3 this year. Last year he was absent from the stage, but now he will be there, probably to promote Metal Gear Rising among other things.
Going to LA for E3 and then NY for signing event at UNIQLO next week.

Shortly after E3, Kojima will visit UNIQLO New York City for a signing event, similar to those already held in Europe earlier this year.
