With only ten days passed since the Steam Winter sale, Valve is reportedly planning another sale really soon. While nothing is officially confirmed yet, it does sound like it is probably happening sooner than later.
A message from Valve to their partners has recently posted on Reddit, announcing the Steam Lunar New Year sale. According to the message the sale will take place on January 23rd and will last for five days.
The same thing happened last year, but instead of January the sale took place in early February. Right now we do not have any information regarding which games will be available for purchase or how much they will be discounted during the sale. We will make sure to let you know if anything changes.
