Translation - they missed their sales projections.
Eh, the last several seasonal sales have had the last day be a recap of the things that sold the best. This is just extending it a couple extra days.
Although, previously, those days would run during
the sale. Not necessarily a bad idea to have this be the Weekend Deal rather than, say, marking Jade Empire down 75% for it, though it does strike me as odd to do it in a way that discourages people who might be looking at any last minute deals from pulling the trigger when there's still a possibility of them going back on sale over the weekend.
Well, whatever the case, I'm crossing my fingers for The Walking Dead to go back on sale, so it'll get price-matched on Amazon and I can use my $5 off coupon on it.
