Well, looks like I called it. After that little stunt of redirecting any traffic that hit the Modernwarfare3.com website to EA’s Battlefield 3 website, Activision has filed a domain dispute and wants the domain ownership transferred over to them. It’s not uncommon for companies to request / file a dispute over a domain name that is either identical to an IP they own. In all likelihood, Activision will win the dispute and the ownership will be pulled. But regardless the damage is done either way.
