The number of sales is likely going to surprise some people by the actual smallness of it all...
But to repeat an earlier point, the 4e core books should be evergreen. The brand should not be resting entirely upon having to have a new release every month. Granted 2 years is a bit of a long stretch to have nothing in support , but the modules should be only a fraction of the total sales, I would think.
They should have been. Amazon (UK) literally can't get ahold of the 4E Essentials DM Kit (I've had an order in for about six months from them). Before Murder in Baldur's Gate the last substantive new product WotC produced was over 18 months ago (Heroes of the Elemental Chaos); the Dungeoneers Survival Guide was half adverts for other WotC products and Menzobarranzan sank without trace (if I read the 2012 State of the Mongoose properly, it sold mid three figures).
This means that Wizards is making its roleplaying money off reprints (no one cares because it's making its actual money off Magic the Gathering, of course). It has basically given away its market share and, worse yet, it has got people out of the habit of giving money to WotC. Getting customers is much harder than keeping customers, and getting customers back is harder still.
