I rarely predict outcomes, but my prediction is that the next round of JI/WA/Wando play will look little like the last, except that JI will dominate Wando again.
H66, the only real advantage in final standings in region 7 play is that winning the region means the 2nd and 3rd place teams have to face each other before having the opportunity to come back around and play the winner. And, generally, home field advantage. At least that's what it's looked like in the past.
