I'm not particularly a Kennedy fan myself, but after the events of Season 7, I don't see them doing a Willow series without Kennedy. But this brings up the question of a series with lesbian lead and a live-in girlfriend. That would be poison to the distributors in the central part of the country.
In an interview with TV Guide Online, Joss was asked about a possible Willow/Kennedy spin-off, and his answer was basically, "first I've heard of it." Having Kennedy move on would certainly help matters along, but I have a feeling that this is one battle Joss would rather avoid.
As to strong words, well... I wouldn't be married to a woman like Faith if I didn't speak my mind, would I?
