Will the PS4 be backwards compatible?

LOL, I was thinking of making the same thread :P

Unfortunately, I think the PS4 will not be backwards compatible because the keys are pretty much public and that would allow everyone to at least play pirated PS3 games on the PS4 from day one (I think)... and the only way to avoid that would be removing backwards compatibility :(

But I don't think that means they can also get the PS4 keys since it would be using a different hardware and a different security system and a different processor... right? or am I wrong? :S

 

OK, I'm starting to think this kind of sucks... if future PlayStations won't allow me to play PS3 games anymore then this is crap. T_T

I don't believe it would allow you to run PS4 games since I believe you're right that the PS4 would have a different key, but by allowing PS3 apps to run you would essentially be allowing an easy way into the PS4 security.  You would be running something that the hardware thinks is official so who knows what that would open up.

Maybe they could limit the PS4 to only play PS3 games from the Blu-Ray player. That way, every game you insert into the PS4 will have to go through the Blu-Ray check first, after it determines wether it's a PS3 or PS4 game, the game will run either on the CELL and RSX or whatever the PS4 has. If someone wants to hack the PS4, they'd have to flash the Blu-Ray drive first.... right?

And they can also make every application (except PS3 games... which can only be run from the Blu-Ray drive) be checked by the PS4 security system or whatever... that would make every application that runs on the PS4 need to be signed with the PS4 keys.

That way hackers will need to first flash the Blu-Ray drive, insert a fake game that's actually an app that allows them to gain access to the PS3 part of the PS4 and then start hacking the PS4... right?

Or am I totally wrong? LOL :P

No, you are EXACTLY right See, each Blu-Ray disc has its own unique code (like a barcode), so the PS3 or PS4 discs can be distinguished differently by one another from the code. I've noticed it with watching Blu-Ray movies, and you are exactly right about that. Once the code is read (and if the PS3 or PS4 is connected to the Internet), the system will confirm the identity of the disc. And like I said with my computer, that's exactly what it does with my Blu-Ray software player does, and it will also recommend similar movies for me to watch as well

The Cell or the graphics card can then alter in performance (kind of like 'downgrading') when it has to play a PS3 game. The Cell will fluctuate to suit its needs; it's how a lot of computers are these days. The performance of the hardware will change to meet the needs when running software.
