If you keep NEO at the time of the fork on exchanges, you will not get NEO Super (Only if exchange itself adds support NEO Super).
Do you have a list of exchanges which are going to support NEO Super and accrual it to their users?
I hope that binance or bittrex will accept fork of NEO. Because I don`t hold my funds on not safety exchanges.
I think now there are practically no people who hold tokens on exchanges. Even if it is such reputable exchanges as binance or bittrex
