I've been thinking about it and I think 6th edition might pull away from the base-sub categories and might unify races and class into 3 parts instead of 2.
You see how warlocks are broken up into 3 parts.
- Warlock Class Features
- Patron Class Features
- Pact Class Features
I thing that all races and classes will broken up into 3 parts instead of 2. This allows for some of the features and cultures that don't have to be smashed together to be separated. It also fixes issues with character concepts coming online too late, balancing multiclassing, creating new versions for various worlds.
So I see 6th edition going
- Race- Dwarf
- Subrace- Surface
- Culture- Mountain
- Class- Cleric
- Subclass- Warpriest
- Specialization- Forge
6 for 6th.
This allows for DMs and players to imagine their worlds better. And it allows for WoTC to sell more books. You can drop Sea or Ice on an elf,a goblin, a giant, or a demon and quickly convert a PC, NPC, or monster. But you have to buy the Sea book. Or the PsuedoEgypt book. Or the MTG book.
