Rumour: Is the Steam Summer Sale starting tomorrow?

The social media account for Paypal has (once again) unveiled the beginning of the Steam Summer Sale. According to them, you can throw your hard earned rupees at Valve's big sale tomorrow, June 22, starting at 6PM BST / 19:00 CEST.

Paypal seems convinced that the start date is accurate, and they were right the last time they 'leaked' the dates, but we have to regard this as a rumour for now, at least for as long as Valve hasn't confirmed it.

Are there any games on your wishlist that you'd like to pick up this time?
