Ubisoft has confirmed that the Prince of Persia Trilogy HD will be releasing on PSN in North America. The three games were only announced for release in Europe on Blu-ray previously.
Along with Prince of Persia: The Sands of Time, Prince of Persia: Warrior Within, and Prince of Persia: The Two Thrones, there will also be the first three Splinter Cell titles getting HD remakes. No release details were revealed for the Splinter Cell trilogy, however.
