As we are all aware $ony are severely lacking in the ideas department. This being the case $ony usually chooses to simply "borrow" from other companies during the design phase of a product.
A prime example of this was with the design of the PS3. Clearly the design was inspired by the excellent George Foreman grill. Now some would argue that the PS3 was actually based solely on the standard issue hotel room trouser press but a clear "winner" has never been decided.
So what is your prediction for the PS4 guys? Which kitchen utensil or household appliance will the PS4 design be based on?
