Hulu Plus service, and neither Hulu nor Sony were willing to clarify that requirement with Joystiq. This week, we've confirmed with Hulu that it's emailing customers a statement to address the "rumors" and "remedy the situation." We'll cut to the chase: "The Playstation Plus service is only a requirement during the preview period," according to Hulu.
That means that during the Hulu Plus preview period, you need to be a member of PlayStation Plus to access the service on your PS3; however, with Hulu Plus currently in its "preview period" and "launching to the public very soon" and the PS3 app nowhere to be found for PlayStation Plus subscribers, it's not clear how many potential users there will be on the PS3 before it goes public. Full statement from Hulu after the break.
