What's Nintendo got in store for Smash Bros. on Wii U? New features? DLC? Ridley?

We'll find out at least some of what will be different in the home-console version of Nintendo's mascot fighter tonight at 6pm Eastern, in a special Nintendo Direct that the folks behind Smash say will reveal 50 new things about the upcoming Wii U game. You can watch it live in the video above, which should start as soon as this thing starts. Hope it's good!
