I may be way out on a limb here, but the Star Wars card game I have always wanted, and believe many others would like as well, would be a character-based combat game simulating a lightsaber duel. You would have a card representing your jedi or sith, a la Raw Deal, UFS, Highlander, etc…and your deck would be attacking, defending, and other cards. THAT I would buy in a heartbeat.

The only game I have like that is battlecon From level 99 games. It's more based around a 2d fighter than a lightsaber duel (so everyone has fireball style attacks) but it has positioning and different speed attacks and all the characters feel different. I think it'd be easy to custom build some Jedi and sith for it if you owned a copy as there are blank cards to use. There's a free print and play of it and a free iOS app, check it out.
