I'm not sure exactly how the demo will work at San-Diego comic con, so this may not be relevant.
In Smash Run, you get trophies, powers and custom moves at the end. I would recommend for those going to keep a sharp eye on these. The trophies may show off other series that may get more content in Smash. For instance, some were saying they say Mechon trophies (from Xenoblade) in Smash Run. Perhaps there are Rhythm Heaven trophies too. Also, it may be nice to at least know the names of some of the custom moves. So keep an eye out ya'll. And don't mash through the end of Smash Run either.
