Because New consoles need BC in their early life. Otherwise it will just collect dust with the 1 or 2 launch games you have beaten while you wait for the slow trickle of new games.
I remember the early ps3 days. Gaming sites recommended people to buy FFXII and God of War II for the PS3 because of BC! --- "if gears can be done on the 360, than any game can be done on the 360" (Wisdom_Cube) "I am the content doesn't inst rest me yet"(theroc500)
No way in hell it will play ps1 or ps2 or ps3 games in the form of physical media. No chance in hell.... I do think they can offer them up on the network as they've been doing, though. the only way you're going to be able to play those games is by buying them digitally... That's just that. That or streaming them. Sony made a lot of strides and prep this gen by offering a lot of their games on the store digitally -- This wasn't just for the sake of doing it. It was done because that is the direction the Ps4 is going to take.
Be it the cloud or the psn store front or Gaikai... Games, Ps1, ps2, ps3 and psn will be delivered in one of those methods. --- Sophistication is buying ALL of your games digitally, but it's more than that. It's a way of life. it's having the best games and telling the world about them
I'd be willing to dump an extra 250 into ps 1,2,3 comparability... hopefully it doesn't take 2 years for the ps4 to have 10 decent games like it did with the 3.... --- Beauty is the only truth in this world.
For PS1 and PS2 games, I would say yes, the PS4 will probably be powerful enough to run emulation for those games. For PS3 games, it will probably need built in PS3 hardware. --- "It would be the stupid comment about the a-bombs that the US dropped on Japan that is offensive."
