Iron Man movie peek

Here's a peek at the gray Iron Man armor in the upcoming Iron Man movie by Marvel Entertainment. I'm assuming this may be either the armor Tony Stark builds while a captive in Afghanistan, or the second version, as the plot premise specifically states there will be 3 stages of armor development, with the third being the red and gold that we are familiar with. I think keeping to the comic history we'll see this armor, then the gold, before we see the red and gold.
