I think the possibility is there, but I think it's unlikely. Lucas is such a "I don't give 2 ***** what you think so I'm gonna do what I want" kinda guy. I think he'll likely go onto some flops and retire.
SW on the small screen is possibly gonna have a huge future though. With the mini-series CW winning an Emmy, it's a viable source... Just has to be done right. What's the odds on that one in Vegas though? I mean, it'd almost hinge on Lucas's personal involvement.
Hammil's talk of 7,8,9 was old news... Nothing new in his words that haven't been uttered somewhere else down the line, so I think it's just got everyone's panties in a wad over anticipating SW hype for another decade or whatever. Lucas says no to that though, so that's what I agree with till he changes his mind again and claims he never said "no 7,8,9" at any point.
