I have a hunch I am investigating. Something happened the same day, parallel with the WoW Commercials. I will update when I have confirmed my hunch.
Note: Some fans have been contacting me. Sorry, the hunch isn’t about any beta nor about Diablo 3. Just something I found curious happening simultaneously. I won’t know for sure what “it” is until a few hours or days. Might be nothing.
However, remember I had a hunch there would be a World of Warcraft comic book 10 days before it was officially announced.
