It looks like Chevy57 edited the original quote.PS3 doesn't have a built-in CC decoder (computer chip = hardware) since it's not a 2014 model but I am not sure about PS4 which will be for sale starting on 11/15. Is it a 2013 or 2014 model? If it's a 2014 model, it should include a built-in CC decoder. That's my concern.

PS4 is 2013 model because it made in 2013, so 2014 will be after Jan 1, 2014.
You could contact Sony and question about add software CC decoder to OS.
Apple TV has software CC decoder, even MacBook Pro too.
