Smash Lord
I was just going to say that.Don't forget either that Nintendo could look at Smash and decide "Okay, we've made enough from this."
If they deem the time right they could just stop making it for whatever reason, as long as they made a fair proift. So if they think that they won't make enough to contunue Smash without Sakurai, then they could not even bother putting money into a sequel.
Sadly, even the best of the best things, come to an end. If nintendo feels that another sequel is just too much,,, or even when they would sell millions, the development of it would be too torublesome, im very sure they will leave brawl as the last uber succesfull game of the franchise......... and start a new franchise.
