PS3 or ps4 whats the difference?

What are some differences?

Well one of the main differences is the price, now u can get a ps3 for just $199 whereas it'd cost u $750 for a ps4, as u can see the price is going to be a huge reason people would choose ps3 over ps4 but u may ask whats so good about the ps4 and whys it so much more. The ps4 is so much more since its newer so the ps3 price was lowered the main difference with the ps4 and ps3 is the visual imagery since ps4 is higher quality.
