I don't believe they will be so stupid to continue with this realID. With all the negative press they have 2 choices imo:

- persist with the realID and face a bunch of law suits, eternal QQ from their userbase and face the beginning of the end
- stop this crap and use it to their advantage: 'we listen to our userbase and value their input ... blablabla' and come up with another solution

Gonna keep playing the game as long as I enjoy it, and as long as my account name ain't visible and I can pay for the game with cash/paypal (i.e. buy gamecards anonymously).

That doesn't mean that I'm sitting back and do nothing. I voice my opinion against the realID wherever/whenever I can. Because I believe if blizzard succeeds it's the beginning of a new era and many more companies/websites copy it. It will change the way we use the internet.
