It looks like IGN has leaked the trailer and release date for Kingdom Come: Deliverance 2. Yes, Warhorse's new title, which will be officially revealed later today, is actually a sequel to Kingdom Come: Deliverance. Not only that, but the game will be released later this year.
So first things first. The title of the new game will be Kingdom Come: Deliverance 2. So a good guess is that it will continue Henry's story. Although the leaked video is of low quality, it appears to be Henry appearing in it.
In theory, the full trailer for Kingdom Come: Deliverance 2 will be longer. After all, the leaked trailer is from a YouTube Short.
Unfortunately, it is still unknown if the game will use CRYENGINE or if it has switched to Unreal Engine 5. Kingdom Come: Deliverance was one of the best looking games of 2018. In theory, the team will stick with CRYENGINE as they are familiar with that. If so, Kingdom Come: Deliverance 2 could be one of the very few current-gen titles powered by Crytek's engine.
