Frictional Games is Teasing its Next Project

Very recently, a website called http://nextfrictionalgame.com/ has appeared online. The website only shows a system seemingly loading something and it is increasing in percentage every once in while.

As of right now the “System” has been “Booted” 45% as we are told to stand by.

Just what are Frictional Games up to?

What do you think the new game could be? What theme is it aiming towards?
