Troy recently mentioned Coinbene is no longer under listing consideration and logos of Coinbene and IDAX have been removed from the website except Binance and Huobi, but there is no way they will list WPP at the current state. Don't know why WPP didn't apply atleast for Bittrex and UpBit as it's completely free and would bring extra liquidity.
I have never seen any crypto project announce a listing on a big exchange prior to the actual listing.
There are always NDA's in place and breaking those will break a crypto-project. I'm guessing we will see at least one more exchange trading WPP before the end of Q1 2020.
... just guessing.
