Thanks to riot's shitty formatting all we have seen up until now is:
Asia vs Asia
Asia vs Asia
Asia vs Asia
SA vs SA
EU vs EU
NA vs NA
6/16 matches are regional
Then you can also divide the groups between western and eastern (funnily enough FPX is the most eastern Western team). And if you do that then you'll realize that only 5/16 matches were between these two regions. Ain't that something. And now with half the asian teams out, we can only hope PRX and DRX make deep runs.
