adding backward compatibity?

If sony cant do a software update to add backward compatibitity, can they make and sell a hardward device that can hook up to the ps4 that can play ps1, ps2, ps3, and umd games? They can probally can sell it around 200 to 300 and maybe sell it also as a external hard drive for the ps4 adding more memory for games.

No need for hardware when they're going to be streaming those games with Playstation Now.

They can't add PS3 games to the PS4. Because of the Cell processor. They will all come digitally

@joseph_mach: I thought they where only going to be streaming PS3 games? Ah live and learn I suppose.

@robdacool: So far, it is PS3 only. For now.

PS Now will not be available in all regions, and there will be a lot of people who will never be able use it. And some that won't want to use it. Streaming is not appealing to everybody.

I wouldn't rule out software emulation for PS1 and PS2 in a future firmware update. Considering the value and appeal of the PS1 classics range alone, I'd say it's a good bet.

it isn't as simple as you think. they stopped making the PS3 backwards compatible because they were losing money on every sale. if they made the PS4 backwards compatible, they would have to raise the price of the PS4 so that they wouldn't lose money. its really not worth it anyway since just about everybody has a PS3 and you can get a PS2 for about $50 now. if someone really wants to play PS2 games then go get a PS2. they aren't that much anymore.

I wasn't even aware PS Now would include PS1 & PS2 games ever. Well good news as a PS1 collector, that if they never add BC the prices of PS1 games wont go up lol
