You can always give Warhammer Battle a try. Ive played a couple of games and found it to be quite enjoyable. There are 3 types of Battle one can play: Fantasy, Sci-fi, and LOTR. All are enjoyable and the miniatures are second to none.
Sorry to hear that "Wizards of the Coast will no longer be supporting the D&D Miniatures skirmish game." I'm not surprised, though.
