My suggestion to Mike Mearls and the team working on D&D Next over at WotC is "modular, but separate".
The Mage class would still have "Wizardry" and encompass magic systems that are very similar to it such as the High Sorcery in Dragonlance, Preserver magic in Dark Sun, Wild Magic, etc.
However, all the classes that are really different, would stay separate classes, but would maintain the modules such as 'Sorcery', 'Invocation' (better than 'Witchcraft' for the Warlock), etc. The classes would line up and be balanced with the Mage on their subclass progression.
The classes themselves would have their own progression tables that better reflect their respective classes and would not have the abilities that fit the Mage such as Brew Potion. The classes would have things that make them unique such as the Warlock's ability to wear armor and Eldritch Blast.
I think this is a good compromise. The modularity of the spell systems stay the same without the extra redundancy of placing them elsewhere for the Wizard and we get our separate and different classes. The PHB is already going to be mostly filled with the same information regardless, the only thing that would change would be the couple of extra progression tables and the small amount of text giving information such as hit points for the Warlock and Sorcerer.
