The Fall Steam Sale will start on November 26, a day before the US Thanksgiving Holiday, according to Paypal.
With the Winter Season approaching, various Steam sales, GoG sales, Humble Bundles and Bundlestars are on the horizont, preparing to strike at the wallet. The Steam Autumn Sale is probably going to start on November 26th, which is something to be expected, if you followed previous Steam Sales. Thanks to PayPal, which has leaked the sale's start and end dates, we have time to prepare the wallet for what is about to come.
The Steam Fall Sale will start on November 26th (a Wednesday), and ends on December 1st (also known as 'Cyber Monday') according to PayPal (and VG247 who noticed it). As such, the time-frame also encompasses the US Black Friday.
Now, PayPay's vested interested is the Steam Wallet cash, and while Valve has not yet officially announced the Fall Sale, it's very likely that they'd reveal said information to companies that act as secondary payment methods.
Here's to hoping that some great on PC, Mac and Linux will be made available. Since Black Friday is part of said date, expect some more ridiculous discounts on the date.
