I've also been eagerly awaiting the timeline videos! They were by far my favorite element of the website pre-launch (I was in the beta since summer so content updates got boring, lol). But seriously BioWare just does brilliant storytelling.
Oh and even though I really love the cool artwork and comic book feel to the timeline, I think it would be cool if what Dark Mantle linked to was a cinematic for the next timeline video! How awesome would it be if they continued the timeline in CGI cinematic form?
