I don't think this will happen..
Just imagine:
On E-Bay: PS3 - for 500$ - you can play this games also online - Killzone 1,2,3, Uncharted 1,2, God Of War etc.. (this wouldn't help Sony)..
So..let`s try to think about this :
1. Codes will be controlled by matching from blue-ray disk.. -> Nothing hard to create Keygens.
2. You will need to phone someone for enabling the game to play -> What if you live in a contry, where sony doesn't have a support ? Will i need to call in another language to an another country ? uff.. i don't like to see the bill then :(
3. PSN verifications -> there is a big problem.. -> As hackers have the master keys, it`s nothing really hard to pretend, that you have legit copy (see XBOX user, which have flashed xboxes and played till these days on live, but you need to flash your drive and so on-> So M$ have many more ways to see, if you have pirated the game.. SONY-No..if you have masterkeys, you can do everything without to by spooted) ..
4. Verification thru SONY servers or creators servers -> Will it be really hard to make an emulator on a PS3, that would emulate activations ? I don't think so..
How can sony see, if you are pirating games.. (need to play online offcourse)
1. PATCHES - yes, you can patch a game then play it online - sony can check HASH(random files)
2. For now, you need to have un-original firmware - Sony have to find just a way, that you have an unofficial firmware - HASH, changed files and so on..
What if you are offline
There is NO CHANGE for sony, to stop PIRACY.. More people would like to play online than offline, so they WILL BUY games for the PS3. The serial method doesn't change everything and it only make legit customers angry..
There could be a changes, that you have to approve the game first online -> (see Lost Planet, Battlefield 2140 for PC).. But i don't think, this will happen..
The more I read the "console flamewars", the more i love my dreamcast :D
