What is the problem of you having a ticket?
You can have the ticket and not have the game.
Is it illegal to add software (just the ticket) to your console? Guess not.
So even if you have the ticket, they will not be able to block you.
And if they do, all it takes is a format of the console, or deletion of the "pirated" game, even if the ticket stays on the console. The ticket is no property of Nintendo. Only the game is.
Will Nintendo brick your console? I bet they won't. Never ever. They would loose game sales, they would gain a bad image, as people would see hundreds of consoles broken.
Will Nintendo block your console for online? Well, even if they do, just format the console. You will get a new console Id, new Friend Code, and a fresh new nand. Even the the ticket is there, it does not proof that you have broken any law.
All this FUD started because bushing was not happy with the disclosure, because it would probably force Nintendo to speed up a bug fix. Now everyone is freaking out.
At most, Nintendo will just fix all the bugs ASAP and strengthen the security of the console, leading to no pirated VC games, no homebrew channels and no more trucha.
You all have to relax.
