Yeah, the truth is that neither Kinect or Move have any real proven killer apps coming out in the near future, so it's mostly a crapshoot at this point.
I'm sort of interested in the engine behind Sorcery. Whether or not Sorcery turns out to be a great game or not has yet to be seen, but I still think there's potential there for titles following in its footsteps.
I'd personally love to see a "magical girl" type of game be made with the engine (although I would prefer it if they gave you the option of which gender to play as). You could use your magical wand to access different powers/spells and use them to fight off bad feelings and the forces of darkness, and make the world a happier place. And best of all, the whole game would be done in a bright and colorful anime style. ^^
I know you guys might not appreciate my idea as much, but this really is what my mind immediately jumped to imagining after seeing the Sorcery demo at E3. =)
