https://www.pcgamer.com/steam-summer-sale-2018-is-set-to-start-tomorrow/ > The word on the street, courtesy of the Steam Database Twitter account, is that the legendary Steam Summer Sale will start—gasp!—tomorrow.    > "Mysterious" Steam cards appeared on the site last week, bolstering the likelihood that the leaked date is accurate, but of course it is: Steam sale date leaks are as regular and predictable as the sales themselves, and I can't remember the last time a leaked date was wrong. Precedent also backs it up. Last year's Summer Sale started on June 22, and in 2016 it was June 23. You might see a pattern emerging there.
