Ropieee Wifi - List of supported Chipsets

Hello,

i have be Pi 3 successfully setup with onboard Wifi. Thanks that was really easy to do. I saw couple of comments there might be some addtional chipset supported moving forward.
As I wanted to put the Pi in a metal case I was wondering which Wifi Dongle to by.
Is there a list of chipsets availble that might be supported moving forward?
