Steam Summer Sale Dates Have Leaked
According to some dudes on Reddit, and we're choosing to believe them here, is that the Steam Summer Sale for 2016 will begin on June 23 and run until Independence Day on July 4th.
Obviously, this is still unconfirmed by actual sources but the rumor comes from somebody who is known to have good information. The user posted an image with the information.
A similar leak happened last year when the dates were leaked on VK which is essentially a Russian version of Facebook.
