I watched the video a second time, and have revised my opinion of the radial menu. Freakie1one brings up some valid points. Since time only slows when you want to make tactical adjustments, it may be more advantageous to have the commands closely clustered, where the action is taking place. This way, you do less navigating with the mouse. Having commands stretched along the bottom may not be the best format. A nice touch would be to allow the player to adjust the transparency of the menu, like we can in Fallout 3. I know from experience I would personally want the menu to be as transparent as possible.
