They are preparing a video to teach new images shortly before or just when you can place your pre-purchase on Steam. Efforts are made with Steam by Dave Cox and JP Konami, they put the dates. But it is assumed that policy Konami will be 1 month before the game's release. So for 24, 27 or 28 January will have this new video, very shocking because he wants to climb up the hype pre-sales, there is another video done that should have been taught last January 10 (show the dragon and the toymaker) along with new images. At the end they simply distribute a video of gameplay for publishers and the the new images.
It is unclear if they will teach this video next week or longer wait to February, it would be too much information in January and they have more things you publish to date on February 21, where the information will be cut. I think this video delayed until February and publish on the pre-purchase day the video that are made it now.
