Well, not so much. Call of Duty: Modern Warfare 3 may not even be out of the gates yet, but is already under ownership to some random Battlefield 3 fan. Given the trouble that Activision went through to get the ModernWarfare3.com URL back, you can bet that the company will be a little quicker on the draw with the legal notices this time. Still, you have to wonder -- maybe they just need to claim every URL that would possibly exist for future Modern Warfare games?
From the website, a short Q&A from the URL owner:
Who owns this site?
Are you Activision?
