I checked the TaleWorlds forum again and realised Captain Lust had stated something earlier; as far as he knows, he says, there will be a 20 minute slot for Bannerlord in the livestream. So we certainly won't see all of the footage live, but he also said the whole thing was going to be recorded and we would see it at a later date, probably one or two weeks afterwards.
@Sinjide; I wouldn't worry about the console port, I am not sure it has even been confirmed for Bannerlord. As I remember it, the brief mentions it had in interviews said that they were considering it, though they have said Warband is definitely going to be on Xbox and PS4. Also Armagan has stated that if Bannerlord is ported to consoles it will be after the PC release of the game and development will not be influenced by the console port.
