Your forgot the lunchmeat.It is not as if we have not seen Dragon Dice, Spellfire and Needlepoint kits as a way to expand the DnD brand already.
(Yes this was a real thing.)
It's just during late 3e and much of 4e, WotC doubled down on the RPG and didn't expand the market. Everything was focuse on the RPG as a product or accessory. The side games were less prevelent.
