D&D 5E is an abstract entity with no needs.
People who play 5E need other good players, who bring joy to the table. And/or bring pizza.
Wait, you mean written products? Some 5E players might enjoy a conversion guide. After all, there's 30 years worth of non-5E material, settings races items adventures adversaries classes locations etc. Some Friendly Local Game Stores have a shelf with old gaming materials available at discount. Some of that material is brilliantly written and would be lots of fun, the moment you convert it and add it to your 5E game. Such as, for example, any of the various rules sets describing psionics.
Hasbro needs more total sales and net profits.
