The thing about us gamers, is that we are an impatient bunch. Most often when a new game comes out we want to play it immediately. But we also have new consoles coming out, and we want to make sure that we have something to play on these new consoles. Too bad some of the most anticipated games of the season will come out before the new consoles are released. Sony is well aware of this and has come up with a compromise for us.
They are offering a program with four games, Battlefield 4, Call of Duty: Ghost, Assassin's Creed IV: Black Flag, and Watch_Dogs. Now Watch_Dogs is a bad example of this as it comes out on the PS4 before it comes out for anything else. But Black Flag and Battlefield 4 come out on 10/29/2013 while Ghost comes out on 11/05/2013. So if you buy any of these 4 games for the PS3, you will get a digital copy for your PS4. You don't even need a PS4 to get it setup. Instructions for this can be found at Playstation 3 to Playstation 4 Digital Upgrade Program site.
