Nope. And why would we want them too? It was apparent all three shows that ran seven seasons were running on fumes by the end.
I agree that ST:TNG was literally running on fumes at the end with a very poorly done last season.
DS9 I thought was severely handicapped by the "let's give Ezri Dax a bunch of episodes to catch her up with the main cast".
While I loathed Voyager, I thought there seventh season was actually somewhat better than previous ones.
