Hideo Kojima has tweeted the first image from Metal Gear Rising
As you can see, there is a crouching soldier and a tank and some mountains. The crouching soldier remains outside a box, which is a good thing. The graphic palette is standard 'Current Gen Mnnngmpf". The tank appears to be facing away from the soldier.
Basically, it's a screenshot.
