If you go to the official site and click on the UK location when it asks where you're from, you'll get a different site than if you click on United States.
While the US site has the timeline, the UK one (or maybe just everything but the US one) has a little bit of back story after the Chimera break out of the Red Curtain and follows a woman as she experiences the war. When the site loads, you'll be asked for your date of birth and be given a choice to enter the site or 'experience' (there is a creepy clip of a girl).
I don't know if it's old or new, but the 'experience' is a cool and creepy little prequel to the start of the first game. It's similar to the Project Abraham thing going on now.
Also, I believe the US website has had some timeline changes as well.
*edit*
Lastly, the next soldier has been selected by the people who view the site (the voting section is at the bottom of the main site). From the countdown, it looks like we'll get to see what happens to him in about 2 days and 15 hours time.
