Only the ones that drop from 3.2 on will always be 2 handed. It is implied that the current one handed Brands, Scepters, Cudgels and Wands will stay in game and that in future patches they will be adding 2 handed crafted versions.

I believe you can still glamour 1 handed weapons on to 2 handed weapons. The only difference is that you can not have a shield when using a 2 handed weapon glamoured as a one handed weapon.
