ESP guitars will be introducing two new Metallica signature guitars at NAMM 2011, from James Hetfield and Kirk Hammett.
NAMM (National Association Of Music Merchants) is one of the largest music product trade shows in the world; not open to the general public, it is designed for members of the music trade business and invited guests.
James Hetfield Snakebyte

The James Hetfield Snakebyte is a brand new body style for ESP and LTD in 2011. It has a set-neck construction at 24.75" scale, with a mahogany body and neck, and an ebony fingerboard with 22 XJ frets.

The Snakebyte comes with a bunch of high-end components, including Sperzel locking tuners, Schaller straplocks, a Tonepros locking bridge/tailpiece, and EMG 81 (bridge) / EMG 60 (neck) active pickups.

You can get the James Hetfield Snakebyte both in ESP and LTD versions, and both are available in two finishes: Black and Snow White, featuring a pearloid snake inlay on the fingerboard.
Kirk Hammett Signature Series

Another limited edition Kirk Hammett Signature Series model is also being introduced in 2011. The ESP KH-2 SE and LTD KH-SE are special edition guitars that will be limited to just 100 and 300 pieces worldwide respectively.

Highlighted by a brilliant Metallic Greenburst finish, the ESP KH-2 SE offers neck-thru-body construction, a 25.5" scale, an alder body, and maple neck with rosewood fingerboard, 24 XJ frets (with frets 17-24 scalloped), and green pearloid skull inlays.

Other high-performance features include Gotoh tuners, EMG 81 (bridge) / EMG 60 (neck) active pickups, and an original Floyd Rose bridge. The LTD KH-SE has a bolt-on maple neck, a basswood body, ESP tuners and pickups, and a Floyd Rose Special bridge.
