1) Who takes second next round? Fox or Meta-Knight?

Fox. Meta Knight impressed, but Fox was amazing... he doubled the guy who was supposed to be competing with him.

2) "Do a Barrel Roll!" vs "You'll never defeat ANDROSS!" ?

You'll never defeat ANDROSS!

3) 4-way match of the day : Fox vs Ness vs DK vs Zelos. Who do you take for 1st and 2nd?

Fox > DK, I'm guessing. DK would try to find way to choke, but I can't see him losing to Ness.

4) Oracle question: how tough is it to predict this contest, regardless of the scores.

It feels very tough. Coming up with percentages is hard, and then every day it seems like I'm doing bad... until I realize that everyone else is too.

5) lol Wario. Alright, that's not a question but I can't stand him =P

Indeed!
