SamMikkelsen: The only reason you'd be seriously concerned about the patches having to be registered is if you plan on pirating the game on release.
Actually, I was planning on purchasing the game even without ever having played the first one until I heard about how patches would be handled. And it's not so much the registering, it's that they can't be backed up.
But yeah, thanks for saying you know me more than I know me.
And of course, while I am playing other games the pirates will be playing The Witcher 2 patched to the newest version available.
