ArenaNet just announced that as part of their upcoming camera changes planned for Guild Wars 2, a first-person point of view will be included. The update is planned for release on March 10.

The first look at the new view will be shown on the "Ready Up" livestream this Friday at noon (PT). A few of the early details on the new camera system were revealed.
Changes and new features coming to the camera system include:

First-person Camera
Zooming in all the way will allow players to experience a first-person view. First-person mode is available while standing in place, walking, running, jumping, playing PvP and just about anything else. There aren’t any restrictions on where first-person can be used.

Field of View
A much requested feature, the field of view slider is a setting that will allow players to adjust how much can be seen in the game world. Players can use a slider to shrink or enlarge the field of view.

Position Slider
The Position Slider has been split into two different options, horizontal position and vertical position. The horizontal position slider will offset the camera to the left and right. An ‘over-the-shoulder’ view can be created as well to keep the center of the screen clear. The vertical position sets the maximum height the camera can go when the camera is at maximum distance from a character. The actual camera height will adjust the more you zoom in to ensure that your character is always on the screen.

Collision Sensitivity
When enabled, this setting will adjust how much stuff (trees, walls, rocks, etc.) needs to be between a player’s character and camera before the camera snaps in.

Character Height
No matter the race or size, the camera will now focus on a character’s head. This is going to give norn players a relatively taller feeling than their asura-playing friends. This change might affect players who frequent jumping puzzles, so to counteract this, there is an adjust camera to character height toggle. When unchecked, the camera will move to a consistent position above the character’s feet, regardless of how big or small the character is.
