These are all owned by Blogsmith Media, a division of AOL. They also write a slew of other blogs, including Engadget. They never go about silly publicity such as that; and if it's a rumor, they tag it so. Also they update articles even after they are published. A true, fair and balanced blog.
PS - IGN is really just about the only people who make stuff up. Any article from IGN should automatically be considered null and void, no matter what the subject is. NEVER, EVER trust a article from that site, as later an official announcement will be made completely opposite IGN's made-up publicity bullshit, and you will be the one who get's moded. I've been there. Other OTers have been there. It ain't pretty.
