I'm not sure if this would happen, but I'd like a new version of Yoda's hut. A bigger one with more room and with a back, I mean. Also, I'd like a new version of Yoda, with a new torso, a cape and a detailed head, like *vader* 's version. In this way I would have a useful set with a useful minifig. I don't care for the price, as long as it's done well I'd buy it.
Then Lego should make a new Grievous, Kit Fisto in a cheaper set, Aayla Secura (in sand blue and with removable "hairpiece"), Darth Nihilus, Asajj Ventress..oh, what about Khaleen Hentz? It's waaay too bad that she'd be a fleshie....
