Yoshida said that when the game was announced in 2009 for PS3, they thought they were making good progress.
“But in 2011 the progress became super slow. There were lots of technical issues. The game was not performing at speed. The video we showed, the trailer on PS3, was specced up. The game was running at a much lower frame rate. Some features were still missing.
“So it was clear that the team had to make a compromise in terms of features and number of characters so while they were taking time, the engineering team ported the code on the SPU [processors of the PS3] to improve the performance, but it was taking lots of time.
