the reason stuff goes on sale is usually to combat rivals in similar market or to get rid of overstock
overstock is not yet an issue for valve but once competition rolls in they might go for a holiday sale to thin out their stock and to stay on top of competition in terms of sales
valve isn't the stereotypical sell sell sell company because they don't have to but they are still a organization made to provide service and to make profit so there are still rules of marketing they follow
sales are unlikely but wishful until they have more stock than they can sell or a big same price range competition reels its head into the market not sure how competitive their business model is in terms of snuffing out competition by timing a sale for their products release or anything
tldr; most of the time sales occur when they have too many products gathering dust, a holiday season where they can sell big arrives (and they have what to sell) or when competition puts out something new
