If I remember correctly Sethi or Shahryar last time said that 6th team will be from Kashmir Region, Then all five existing franchises opposed the idea. But given over wheleming popularity of PSL, Next season Kashmiri team will be a must
I think Faislabad because they have quite a few top business franchises in terms of the textile industry. 2-3 of these companies can combine to build a very strong franchise
Either Kashmir or do something different and let Afghanistan have their own team. Then add a Bangladesh, Sri Lankan and Indian team for subsequent seasons.
The boards of those countries don't have to be involve. They just need to market the teams as such even if the owners are Pakistani.
