Cinderboy, a writer for OnRPG, recently posted the following article on his blog, MMO Culture:

"On 12th February 2010, TERA released a brand new teaser video on its official website, possibly teasing that the 3rd Closed Beta is near. Included in the short trailer was a glimpse at the development process of the game, the sketches, ideas, map settings and more. As opposed to the previous trailers where CGI and ingame footages were used, this trailer actually brings a breath of fresh air to the much hyped MMORPG. Of course, the date is still not set yet for the Closed Beta, but I guess gamers will not be lamenting since its said to be happening soon!"
