I'm thinking two things.
Games (which obviously we'll see some big names over the next couple years)
The wild card - VR
Sony has been working on virtual reality for quite some time now and I expect to see it as some sort of add on or bundle for the PS4. If it's a hit with the consumers and it's done right with an affordable price, it can take off like how the Wii did in the beginning with it's motion controls, then we could see some explosive sales.
