Yep. WeMade Entertainment launched a teaser site and trailer video for Digimon Battle yesterday. Both are short on details, but open beta registration details are promised "soon", and the company has jumped into the social media arena with both feet. There are updates a-plenty on their Twitter page, announcements and links on their Facebook page, artwork on the teaser site, and the aforementioned brand new teaser trailer.
WeMade has stated that they are planning to release the game in March, so the expected open beta will be brief, and presumably soon. We'll keep an eye out for details, and in the meantime check after the jump for the trailer.
