If they have a patching mechanism already, then it is brutal. Patching the PS3 takes 10 minutes each time with about half a dozen button presses (so it can't be completely hands off). 360 updates, you click yes and within a minute you're back in your game...don't even need to resync your controllers.
PS3 has a long way to go in this area.
Fyi, the resync is gone, no need to connect the cable again.
I would like a one click update on the PS3, it´s the same with WoW, 3! EULA i have to accept with so much text it would cost me 100k in lawyers to understand how many of my kids i just gave away.
