Looks like the Bronycon Documentary has expanded with yet another awesome new addition. Included in an update about a whole wealth of interesting news, it looks like a fully animated song is in the works from Mic the Microphone, Amy Keating Rogers, and David O. When completed, John de Lancie will be performing it with another group doing animation for the entire thing. That sounds pretty epic to me!
Head on over to their kickstarter page for a whole bunch of information on that, as well as other aspects of the documentary.
