The matches will be entirely randomized. I want to make a point of this beforehand.
http://www.random.org/lists/
For example, I just randomized 8 random people, Naith, Majin, Ess, Dripz, Tashkin, DOCTOR OCTAGONAPUS, Knux and Nuke in that order and it comes out in a different order.
knux
naith
nuke
majin
tashkin
dripz
ess
DOCTOR OCTAGONAPUS
So it would have been
Knux v Naith
Nuke v Majin
Tashkin v Dripz
Ess v Doctor OCTAGONAPUS
