Speaking to The Washington Post in an interview, Sony Interactive Entertainment’s Senior Art Director Yujin Morisawa revealed that had the engineering team not tell him, he would have made the console even larger than what it is at the moment. He was quoted as saying, “In the beginning, when I started drawing, it was much larger even though I didn’t know what engineering was going to do. It’s kind of funny that engineering actually told me it’s too big. So, I actually had to shrink it down a little bit from the first drawing.”
The reason why Sony made the PS5 as large as it is, is because of the powerful hardware packed inside of it. According to Morisawa, he knew at the jump that the console had to be even more powerful than its predecessor, and because of all that power, he also knew that it needed even more space to accommodate a larger heatsink and to offer better thermals.
Morisawa believes that Sony has since arrived at what they believe to be the “perfect size”, although we’re sure some gamers might disagree with that assessment.
