They have said 2014. My guess is earliest is summer as a roll out starting in Japan. Hopefully worldwide by the holiday. Smaller regions might not receive it till much later. Major region accounts are a must.

What advantage was there supposed to be?  Paying for a game for ps3 then paying $10 to play an upgraded version on ps4 sounds like a good deal to me.

why not just buy on ps4 for $10 less and you wont have 2 versions of a game as you dont need 2 

well hope you are right,i thought it was some kind of pipe dream turning  up in a few years time

?? This is clearly for peeps who only have a ps3 and upgrade later....................

We'll see how this actually works in practice. I will say that it's a pretty clever solution to allow PS4 owners to play their PS3 games without having to repurchase them outright a second time, which is more or less the current situation with old PS2 games being sold in the PSN Store, albeit at greatly reduced prices.

Most of the PS2 games that actually made it worth having a PS2 BC CECH-A01 console have either been remastered in HD or released in the PSN Store for about $10, which is totally reasonable.

I don't see PS3 games being sold for play on the PS4 for the same $10, but... I wouldn't mind paying $10 to play the PS3 games I currently own on the PS4, assuming the Gaikai streaming actually works as well as playing the game in one of my PS3s.

I think it's going to be some time before we actually see this being implemented though. If anyone was hoping to be streaming their PS3 games by early 2014, they might be disappointed. I'll be surprised if it happens before the end of 2014.

I wonder if they will have the same option as Xbox games. You can own both digital rights to the 360 and One version for just $10 more
