The Elder Scrolls Travels was Bethesda's answer for TES on mobile platforms. The Travels series included Stormhold, Dawnstar and Shadowkey for Java-enabled mobile phones. A version of Oblivion was also made for mobile phones but was not related to the PSP game.
The PSP version of Oblivion was described as a downscaled, more focused version of its console and PC counterparts. In an interview with Todd Howard, Executive Producer of Oblivion, it was revealed that the game would focus more on "dungeon exploration" parts as opposed to "walk around town" parts. 
Oblivion for the PSP was given a tentative release of Spring 2007 but never made it. The game was never officially cancelled and no reason was ever given for its disappearance. To date, no playable build or even video footage has surfaced, and the screenshots from the reveal issue of OPM were the only screens released to the public. Considering Sony's retirement of the PSP platform and Bethesda's lack of acknowledgement regarding this game, it is unlikely to ever see the light of day in any official capacity.
