Considering they update so much and have a ton of connections, kotaku is one of the best places to go if you want breaking news in the video game industry. The problem I've always had with Kotaku though, is that most of their posts seemed like they are geared and written for 13-year-olds and often times they post up a lot of rumors that should be researched a bit more before publishing.
A good place to go to is a site called PSFK. Directly from their site is a brief dscription of what they do best. "PSFK is a global trends and innovation company that helps its readers, guests and clients make things better. PSFK publishes websites and reports; hosts conferences and events; and provides advice and consultancy." This site follows various trends but, they have a section dedicated to gaming that I look at frequently. The writers get right to the point and they often write about things that you won't see in kotaku. Also, their audience is a bit older, so the articles are well-written.
The last odd place that I check is a site that shares and allows you to publish online magazines. I don't plan on making my own magazine but they do have a magazine game section that is surprisingly very professional. Considering that magazines don't publish as fast as kotaku and PSFK, this site is only good to go to every week or so but still, it's nice having a resource that isn't just a blog. The ability to publish is also a plus if you, for whatever reason, are making a magazine.
