Um....what? Once Toriyama dies I'm sure Dragonball will R.I.P.
You're so sure because you know Dragon Ball better than everyone else on this forum? Nobody here can predict what the future of Dragon Ball is. Don't be silly. 10 years ago there were people like you saying "I'm pretty sure there won't be anymore stories within the DBZ universe," and now we have "Son Goku & Friends Return" and BoG. "I'm pretty sure we'll never know who Goku's mother was."
Like I said, if 50 years from now they want to create a new Dragon Ball series or manga, then they have every right to, because Dragon Ball is bigger than Toriyama. Likewise, Star Wars will continue long after George Lucas passes away, despite what die-hard fanboys say.
Lets say in the future they decide to reboot the series in a way that they want every single "non-canon" movie to fit within the "official" timeline. Some of us here will look at that as a bastardization of what Dragon Ball was originally intended to be, but a lot of other fans will embrace it. What's so hard to understand about that concept? I'm just offering possibilities on what COULD happen, and what fans consider canon or not. Once again, nobody posting here is an authority to claim what is canon, because it's obvious we all view "canon" differently.
The only thing everyone here can be "sure of" is that we're sure we have no idea what the future has in store for Dragon Ball, bottom line.
