PlayStation is beefing up the premium offerings on its PS Vue streaming TV service. As of today, HBO and Showtime will be available as part of the new Ultra ($64.99 to $74.99 per month based on location) plan. Don't feel like ponying up that much? Both HBO and Cinemax are $15 per month on their own. A post on the PlayStation Blog says that this is the first internet-based pay-TV service to offer the channels both live and streaming without a bundled package.
