I can't wait for Bannerlord to release based off what we've seen. Speaking for the larger part of the community, I believe we can all wait for the game to release as long as feedback is given to the community on the development. Waiting another six months, as we did once, for another devblog would be really irritating, I, personally, enjoy seeing multiple devblogs within a month.
I personally only want to see one main improvement moving from Warband to Bannerlord besides what was expected from a video game sequel: A co-op campaign
I understand that that would be hard to do as the in-game time would have to constantly be running, leading to problems for the players when they enter towns, battles, etc. These can be solved if the background screen is removed when you enter a location, and the UI replaced with a transparent background. As for battles, even in singleplayer, these should take time to complete as logically a battle involving 300 men on each side would take time and wouldn't end instantly as it currently does. Or, perhaps, a battle would have to be queued on the server, and only available to occur when no other battles are underway. Public campaign servers would be hindered by this, although I am only referring to co-op campaigns which involve oneself and his/her friend(s). In my case, the campaign would only involve myself and another. The server host would have complete control over the ingame time also, he/she would have the ability to play/pause. In a case involving friends, the host having the ability to stop the game at any time would cause little/no hindrance as the pause would likely be communicated ahead of time. Also, putting one or multiple disclaimers when starting a co-op campaign outlining the risks/annoyances/quirkiness the game mode entails would satisfy me. Only a select few would consider the game mode to be, for lack of a better term "dysfunctional", and at that, the singleplayer experience will still be phenomenal.
Keep up the work and as Sundeki stated above, a beta would allow many M&B fans to test the game and spot any bugs for the developers. I believe Vince Lombardi said something along the lines of: "Nothing will ever be perfect, however, by pursuing perfection we achieve excellence". You must understand that your fanbase already knows your game is excellent and we don't want perfection, otherwise we'd never get to play it.
