That last picture definitely looks like a part of the drone and the symbols look identical. I would guess that the countdown is for the release of
Halo 3.

The key to unraveling the paper trail behind the clues was a logo visible on the right-hand side of the image (see below). Many people reported seeing this logo repeatedly cropping up on Halo 3-related websites and so the hunt for cold, hard facts began.
The first real breakthrough came when CrazyBoy3, a poster over at Bungie.net, proved he wasn't so crazy after all when he spotted a Circuit City ad that included the logo and a reference to halo3.com... The comic tells the story of an African man who sees the Sentinels arriving on Earth.
saw AR's symbol there. And it said to go to www.halo3.com/comic
edit: The numbers hidden in the last three comic slides are the IP address to a site. Skim through the first 5 pages and you should be fairly up to date.
