How to lose customers and annoy people...
I had to check the date there for a second. Not April the 1st yet, is it? Bugger.
It *would* be cheaper for them to use an existing CPU set & architecture, but as mentioned, that means the devs have to learn another set of skills.
Also, no backwards compatibility? Again? Seriously? (although again, if they move away from Cell tech, nothing would work without an emulator, and as one commenter suggests, that would take SOME doing).
Unlock codes are sadly also easy to do - buy disc with leaflet, install game - enter code from leaflet and game plays. Code flagged as "used" (ala PSN) and tied to your PSN account, so you can at least move consoles as you can now, in case one dies.
BUT, and this is a big but - at present, if your PSN account is banned, you can still play offline. If you can't validated your games/codes, due to a banned account, you can't play? (as if you are banned you need a new account, etc etc).
Similarly if they also (or alternatively) banned the console, then it's technically useless - are they going to refund you all your money/console etc? Seriously risky propositions ahoy.
So *IF* it's true, it's a bloody stupid idea!
