Two retail print ads have shown what appears to be three PlayStation 3 titles getting the "Greatest Hits" treatment. The trio shouldn't be surprising: Resistance, Motorstorm and Warhawk. A Kmart print ad shows box art with a red banner reading "Greatest Hits," while a Circuit City ad shows the same three games, sans new packaging, for $30. (You can tell it's the most recent ad since Soul Calibur IV is mentioned as coming out this week.) We expect an official announcement at Sony's press conference this week at E3 2008.
