Wow I picked the actual partner for the next zelda game!

Now if all the theories are true about the spirit behind link being the Master Sword, then I actually made a similar suggestion back in January.

I remember a cartoon where someone had a singing sword, so this is where I got the idea about a talking sword. I don't think the sword will mind being swung around. One of the sword's specialties could be to know an enemies weak spot.
It could be like navi where when it needs to talk to you it flashes the button. However it does not shout "Hey" and "Hey Listen", noo, it should stay quiet until your ready to talk to it.

So it looks like we have a talking sword after all.

We don't know if the Girl really is the Master Sword.
Or if she talks.
