I'm a big fan of the 3.5 books Heroes of Horror and Heroes of Battle. While perhaps not a direct update of these books, I'd like to see a book focused on how to run different kinds of campaigns.
I loved the 4E product model for supplements. I'd like to see more 4E style toolkit products (And then I might actually buy something from WOTC)
Examples (not necc 5E versions of the same books)
Threats to the Nentir Vale
For me, it's a no brainer. I'd like to see a 5e version of the 2e Core Rules CD ROM. Obviously it doesn't need to be a CD ROM, but a program that you can use offline that:
-creates and updates PCs
-creates encounters
-includes digital copies of the core books
-basic map making software that hyperlinks to said created encounters
20 years later and I still use the CD ROM for certain things.
If we're going electronic, bring back the 4e offline character builder. Add in support to add in your own material, or import someone else's.
