envisioned by Ueda since around 2005 after completing Shadow of the Colossus, the game was in active development since 2007, a year after the release of the PlayStation 3. The working title was Project Trico, revealed to the public due to a leaked video posted at PlayStation Lifestyle in 2008 that showed the current "Target Render" of the game at that time. Ueda had long considered the development time for Ico and Shadow of the Colossus, and had anticipated being able "to create something good in a short period of time" with The Last Guardian at the onset. By 2009, the development team had completed enough of the game for it to be showcased during the E3 2009, using an improved render of the same set pieces previously seen in the Target Render and later provided a short vertical slice of the game to the press for the Game Developers Conference in early March 2011. Ueda had considered including this demo on the then-upcoming remastered The Ico & Shadow of the Colossus Collection, though it was ultimately not included. Behind the scenes, the development of The Last Guardian was considered slow by Shuhei Yoshida, the president of Sony Computer Entertainment Worldwide. Yoshida explained that the vision for The Last Guardian was based on a video prepared by Ueda to demonstrate the concepts and style of the game, a process Ueda had used for Ico, and Sony wanted to stay true to that vision. Team Ico, which is a small studio compared to other Sony studios in Japan or other Western developers, were struggling with achieving Ueda's vision for the game on the PlayStation 3 hardware. In 2015 Yoshida revealed that the previous 2009 trailer was "specced up", running at a much lower frame rate on the PlayStation 3 and sped up for the presentation. Around 2011, Sony brought in many of their core development teams such as Santa Monica Studios to review the code and try to improve the performance. In 2012, with Sony preparing to announce the PlayStation 4 and still recognizing the sluggish development of the PlayStation 3 version of the game, it was decided to change the target platform to the PlayStation 4 so that Ueda's concept could be fully realized. Ueda stated that this choice was primarily Sony's decision, speculating that the PlayStation 3 version of the game at this point would still have been sufficient
