Oh, yeah, definitely.
It's also interesting to consider. Anyone else in Lucas's position: with six huge-grossing movies that he owns himself... he would be set for life, even considering his divorce. I'd wager that most big-name directors that make 6 films as phenomenally successful as Star Wars would be set for life even if they didn't own the films, and especially if they did. But Lucas has his own company to oversee. And, aside from outsourcing ILM to other films needing visual effects, Star Wars is the only big money-maker keeping it alive. So, unfortunately, Lucas will keep milking the franchise for as long as he possibly can. Granted, it's still too big a cash cow from them to seriously consider ending it anyway, but Lucas does have an empire to maintain.
