Seriously cannot wait to try playing online on the PS4! Sony confirms PSN on PS4 has been massively improved!
Speaking about the PS4's launch: “You’re going to see everything that you ordinarily see when you transition from one console generation to the next. So, improved processing power, better graphics – but I think that the most interesting thing is the vastly improved online capabilities.”
“The ability for people to communicate with each other is vastly improved,” “You’ll be able to watch your friends playing their games, and they’ll be able to watch you. You’ll be able to help them, and they’ll be able to help you."
