Been watching it daily. And yeah, I agree, the two "new new new" characters looks awesome. I also like the scenaries and the items so far (even though I still miss a giant scenario a la Fox spaceship from N64/NGC or the Zelda ones).
Just weird that they have shown various characters in diferent places that haven't been anounced yet (Metaknight A LOT of times, Peach, Snake...)
Oh, and the Final Smash's are really cool.
