Its not much but starting at 1:49, Samus for the first time in history speaks her first words. And yes its very sexy.

Her verbal Taunts include:

"Try Me" Swings her whip around, full circle

"Is that all" Throws her pistol into the air

"MMmmmm" Does a 720 degree spin with the whip twirling around her

EDIT:

The link might not take you to the video properly so heres what to do. Hit Brawl, in the featured section below the video screen then hit taunts on the left.

Or use this youtube link, curtosy of sc94797 (thanks by the way):

Yeah, it's weird to hear Samus talk...it's like hearing Link talk, "EXCUUUSE ME, PRINCESS!"

But it's not that bad...I don't have an opinion on the matter. ZSS seems over-sexified...but I'm not really complaining.

!?!?

Now maybe she can start speaking in the games. She had extensive dialogue in Fusion but the Prime games pretend that she's a mute...

I didn't find the vid in your link but here is it on youtube http://www.youtube.com/watch?v=0N4K4wqZH6A

I like it when she says mmmmmm lol.

Do you guys really think that's sexy? :O

she sounds far too old imo

ha thats cool,i wonder if they will make link talk

 No...and they try too hard to make her seem sexy though...kinda lame...but Samus still rocks, so I don't care.  As long as she can beat the crap out of everybody, I don't care how sexy or not she is.

Not really sexy a little funny though. If they put it in an actual metroid game I would think it would sound better. Maybe the next 3d metroid will have samus voice acting.
