Speaking with Eurogamer, Yoshida explained that there are certain "technical issues" that developer Team Ico has been pushing through since last we've heard of it. "That's the period of time when the game, looking from the outside, doesn't seem to be making much progress." In February, Yoshida made similar promises about The Last Guardian but admitted progress on the title was "slow."
The Last Guardian has failed to appear at any major industry trade show in years, including last year's Tokyo Game Show, E3 in June, and this week's Gamescom.
Trouble started to boil over in December 2011, when Team Ico mastermind Fumito Ueda announced he was leaving his position and would complete work on The Last Guardian with Sony on a contractual basis. Recently, Sony abandoned the trademark for The Last Guardian, but can still recover it by filing a petition by January 2013.
Yoshida says that Sony Japan Studio – one of the teams helping with the project's completion – had to completely re-do work to bring the game to a playable state. "...it turned out the technical issues are much harder to solve. So the engineering team had to go back and re-do some of the work they had done," he said.
Despite its numerous delays, The Last Guardian has not shifted into a new console generation. "The game is developed on PS3," Yoshida confirmed. Let's hope it doesn't launch as late as some of the PlayStation 2's latest software, which continues to arrive six years after the PlayStation 3's release.
