Even more so, since the grand success of the movie the series is getting a revival and an order for about 200 episodes has been made. It's suppose to start after the Buu saga. The movie will probably be inducted into the canon and it'll likely pick up with Goku training Uub.
I didn't see anything personally about this, just what people tell me, so I can't vouch for it's 100% authenticity.
Honestly there isn't much they can do from this point on. They involved the spirit world in the Buu saga, and went balls to the wall to make the strongest characters in history. Where exactly do they go from here?
On that thought, I do believe the ideas behind the GT series were really great. They nerfed goku, and took things out to space away from the OP saturated planet Earth. The overuse of the Draognballs was good, and Baby was conceptually an interesting tie in with the Tuffles. Beyond that, incorporating the Ozaru form back into the series was a great idea, and made a lot of sense. It was nice to see Goku's tail back either way. SSJ4 almost feels like a different transform line than the rest though. I could see it as being the next step for the Ozaru transformation, being able to invoke the form at will, and then also combining THAT with SSJ mode, making a golden haired looking SSJ4 design (or white haired like the hoaxed SSJ5).
But with all that potential, GT was ruined because the execution and script writing was absolutely god awful. The people in charge of actually producing the episodes really had no idea how to handle the source material. They threw out all the conventions of the way things worked in the series, though lose as they may have been, and just replaced it all with 'Saturday Morning Cartoon' logic. Counter to that though, as explained above, the planners and concept guys behind it all seemed to know what they were doing.
Despite that though the final battle was fairly good, and the epilogue was a nice series send off in my opinion.
