Weyland Industries timeline

I don't know if this as been discussed, but a member of this forum (Cybershady) as pointed out that the Weyland timeline as been updated for October 11 2012 with regards to the DVD/BluRay. It seems to have hidden extras that are on the BluRay but i don't think that they are on the DVDs? So for those of you that have only got the DVD, here is the link: [url=http://www.projectprometheus.com/discover/]http://www.projectprometheus.com/discover/[/url] You need to click on the star system icons in the picture to see the extra features.
