Thanks to internet forum Reddit, there’s some (unconfirmed, but credible) information regard when Steam will start their next Summer Sale; which very well may be June 23rd, until July 4th.
As for the leak, it seems to originate from an unknown developer, who may, or may not care about little things like “industry secrets”. While this appears to be a repeat of a similar incident last year, as usual, take with a grain of salt, as there’s always the chance Steam may move the date to surprise people.
