I guess this is one major advantage of console gaming over PC gaming. Your games never expire if the publisher pulls some server...
Don't worry, they'll fix this soon enough. Today's console disks provide copy-protection equivalent to the CD-key checks used in PC games thus far. Future console disks will only be playable on the first 3 unique consoles you first play the disk on. Once you "activate" a particular console, you can play the game on that console as many times as you wish, but if you want to play it on another console you will use up an activation. The idea is to limit second-hand sales (an ugly and downright criminal practice that is rampant in the console space), and to discourage you from lending your disk to your friend temporarily (another deplorable practice). These modifications will bring console DRM on par with today's PC DRM.
ROFL That's a good one!
They would also have to make sure, that if you by any chance change controllers or other hardware or otherwise upgrade the console, it can also use up an activation, but you can never know ahead of time - you have to try it first to see!
Hasn't happened yet, and haven't heard of any plans on that. So I have no idea where you got that idea.
And if it was sarcasm, whoopsies.
