If you didn’t catch the games at MLG Columbus they also have a VOD section uploaded now with all the games included.

Also I just noticed this Q&A from the faction change thread:

Q. Will we be able to switch between the races on our own faction?
A. No. Players will only be able to switch to a race of the opposite faction.

Q. Will I be able to choose the race on the opposite faction that I want to change to?
A. Yes, but you will only be able to switch to a race that has your class type available to it. So if you play a human paladin, you’d only be able to change to a blood elf paladin.

Q. Will I be able to switch back to my original faction but a different race?
A. No. You will only be able to switch back to your originally chosen race.

Sigh. So unless everyone wants to mass-reroll horde with me I guess I’m stuck with a Night Elf for now.
