Fist Weapon Reversal Effect?

So I know in 8.1 we are supposed to be able to mog fist weapons into axes/swords/maces.. But what about those that WANT to use fist weapons? Do you think it will be vice versa too?
I'm assuming and hoping so because I much prefer fist weapons.

I thought the restriction in MoP was around if the weapon had a different combat animation, so if we can have Fists > Swords we should be able to have Swords > Fists?
