Over on ConSimWorld a post by Worthington Games indicates that they hope to have their new Napoleon game based on the Hold the Line system "out" by June 15th.
This would technically mean it's published before the anniversary of the battles of the Hundred Days (QB/Ligny is June 16th), although I doubt that many players will actually get their hands on a copy before Friday's anniversary of Waterloo/Wavre. Oh well. WG reports the printer had a death in the family which pushed everything back a week.
I have high hopes for Napoleon;s War, given that Hold the Line has been so good.
