Worthington Games has a list of upcoming games available for pre-release sale prices on their Website, among them are this interesting one based on their popular Hold the Line system.
I've enjoyed that game systema lot and it makes an interesting contrast to the Commands & Colors: Napoleonics game due out soon from GMT.
The Worthington Games title will use plastic miniatures, shown above, for the battles in the Waterloo campaign. They are generic (as far as uniforms go) and will differ among the nationalities based on color (Red for Anglo-Allied, grey for Prussian and Blue for French), being similar to the approach used in Battle Cry and Memoir '44. The GMT game will presumably use wooden blocks, just as Commands & Colors: Ancients did, which will probably use stickers with the proper historical uniforms as well as block color to show the armies.
The Worthington series uses Command Action Points to limit how many units can be ordered, but players have wide lattitude on which units to order. In the C&C system cards not only limit how many units can get orders, but which ones. Both are good systems.
