The entire game of Super Smash Bros Brawl clocks in about 8GB. The size allowed on a Wii U disc is about 50GB. You could have about six whole copies of Brawl neatly fit onto a single disc.
Oh wait, how big is the content? Well a single custom level is about 5KB. I assume professional levels are bigger due to having unique code to handle stuff like special enemies, events, moving platforms, etc, but it's probably not too big.
And music is pretty small as well, practically speaking. You could get about 200 songs in a gigabyte of space (each file is between 1 and 10MB). Basically, you could theoretically get a music list with about 3 times the amount of tracks as in Brawl no problem. Heck, if you were really desperate and used nearly everything for music (they obviously won't), you could have about 10 000 different stage and character themes. But that's unlikely, no orchestra on the planet would want to record more than a thousand songs.
Seriously though, if anyone really doubts we can have a ton of characters, stages, music, items, trophies and game modes in Smash Bros 4, all I can say is that it seems logical that there's nothing stopping this from being true tech wise.
