There are many improvements done on PSN, Sony had to learn the online infrastructure in the first place before they put the PSN brand in their PS3 console. But they have a big chance for PS4 online infrastructure.
Sony seems to be prepared to lose alot of money, but that goes up again with the amount of games they will sell along with the console. So this a risk.
Since Sony has done many things for good reasons to convince us well to choose Ps4, then we can assure that Ps4 itself will sell well and sell even better in 2014
