Here is a look at Kotobukiya's upcoming General Grevious which is part of their ARTFX statue line. As you can see in the images, Grevious comes with a piece that allows you to attach its base to the ARTFX Obi-Wan Kenobi figure to re-create the climactic battle on Utapau between the two. This version of Grevious has 4 arms and 4 lightsabers.

Obi-Wan is due out in July 07 and Grevious should come out in December 07.
