It doesn’t appear we will get to see the PlayStation 4 anytime soon. According to SCE chief executive Andrew House, Sony feels they have to make a “significant leap” from the PS3 before we see a PS4.
“The right time to talk about new advances in hardware is when you can demonstrate a significant leap on the current experience, and something that is going to be attractive.”
I have to take Sony’s side on this one. It would be a huge disappointment for the PlayStation 4 to be released with no major upgrade to the graphics like we saw from the PS2 to the PS3.
