Japan is full of used PS4 consoles. What's the meaning of this?

They realized that there aren't that many games out for it. One of my friends really regrets selling his PS3 to buy a PS4.

Terrible mistake

I advised him not to, but he's a dumbass. He keeps selling then rebuying a PS3 everytime a game he's interested in comes out. I'm pretty sure he has wasted more than 500$ doing that.
