Griffith Dragonlake said:Why not use the sorcerer class with intelligence as the key spellcasting ability instead of charisma?
Because it might be that the earlier "pre-literate" conceptions of magic were based on personality force and magnetism, and not intelligence per se. The idea of a wizard memorizing formulas and manipulating reality in a pseudo-scientific fashion (with "laws of magic") and so on, like a lot of the modern imagery of the fantasy wizard, belongs more in a pseudo-Renaissance era. So the intelligence/charisma divide between literate and non-literate wizards seems appropriate to me, although I imagine many sorcerers are intelligent just as many wizards are charismatic.

That would be awesome - take all the best ideas that have circulated and combine them into a big rulebook. Something tells me however, that they'll go the 3E route, and just republish older ideas with reworked mechanics in various splat-books over time.
