No English sides.tension between India and Pakistan may mean no Pakistan team.(tensions stopped Pakistani's involvement in IPL this year).
I gather this will mean 1/2 more ipl sides(i am serious),maybe the 5th or 6th side might have to qualify.
Maybe 3 sides from S africa and Australia,not likely tho,India likes to keep the balance their way(idea was raised previously but the BCCI said no).
.I gather the BCCI is pissed since an Aussie side won again.(Even tho it was in S Africa).
Maybe 2 Windies teams,a Bangladeshi side(5 overseas pros in BPL,which BCCI might complain about).,lastly Zimbabwe,not likely,non competitive, overseas pros are 2nd xl county cricket standard.(not 2nd division).
