It is coming. Khal has mentioned it in many AMA's. The Uniswap WLEO/ETH pool will go away and WLEO will pool on ThorChain (paired with RUNE obviously). Khal mentioned making a new LEODex that merges with THORCHain so that you can swap Hive-Engine tokens directly for THORChain assets (kinda like how LEOBridge works).
