Yep the mini cabin is def gone , -300s to go to 30J( doors 1-2, then premium economy for 4 rows in a 2-3-2 configuration , increased legroom etc , then economy to start aft of here.
Not sure about the 200s yet but likely to remain at 24J but also with premium Y, however they generally operate the quieter business routes(snn-US, DUB-MCO and the IAD run )
