How many of you laughed at how credulous news sites are before verifying that this blog post was accurate? Finding a reliable news source is hard, and not just in the games industry. Even here on Hacker News I usually read a headline, wonder if it's true, check the comments for contrarian views, then read the article.
Journalist here. FYI, the day someone I don't know emails me with a "hot inside tip" is a day I spend tracking down the emailer and calling my sources within the target company.
Just so you know, even at the big news sites, good hot tips from unknown emailers just never happen. Great hot tips come from getting corporate employees drunk, then chasing down their leads from other directions when you're sober. Anonymous insider emails spilling the beans only happen when a company is about to, or currently going bankrupt, or some such other catastrophic melt-down. Then they come crawling out of the woodwork.
