I am. Even though my Titan is an awesome phone, I just can't take people telling me that they hear me muffled or distorted. I cant wait! 
Nope. Very happy with my Titan. I don't think I could go to a smaller display size after this.
Nothing about it interests me. It's thicker, the camera on the Titan is more than fine for me, and LTE doesn't exist where I live. All in all it would probably be a worse experience.Titan 2?
