In a recent interview on the PlayStation Blogcast, Stewart Gilray, the CEO of Oddworld revival studio, Just Add Water, stated the team is targeting a late June release for the PlayStation Vita port of Stranger's Wrath.
Development has been going for five and a half weeks and he expects the title to be in beta by early June. I'd say it's very likely it will be on display in this stage at this year's E3; possibly dated there as well.
He also mentioned the patch for the PS3 version of Stranger's Wrath which adds support for 3D displays and PlayStation Move should be out at the end of May.
